Brown dwarfs and rare objects in UKIDSS
Creators: name: Skrzypek, Nathalie
Publisher: name: Imperial College London
Year: 2014

description: When brown dwarfs were first discovered two decades ago, they were introduced as the missing link between stars and giant planets. This led to the extension of the stellar classification sequence down to the planetary regime by introducing the spectral types L,T and Y. We are now in the era of brown dwarf science where large homogeneous samples can be produced, allowing us to learn about their physical properties in a statistically meaningful way. In this thesis we present a new method, dubbed photo-type, which makes the classification of L0-T8 dwarfs significantly faster as it only relies on already available multi-wavelength photometry. It is based on χ2 template fitting and can be adapted to use on any photometric data. photo-type classifies L and T dwarfs to an accuracy better than 1 spectral type, making it comparable to spectroscopy. This is tested by a range of different methods, ranging from simulations to spectroscopic follow up. By searching the SDSS+UKIDSS+WISE for L and T dwarfs with 13.0 < J < 17.5 we produce the largest homogeneous sample of these dwarfs to date. These 1157 L and T dwarfs are used to find peculiar objects and populations (e.g. blue/red outliers), L/T binaries, and benchmark systems (by crossmatching with a proper motion catalogue). It also allows us to calculate the best estimates of the space densities of L and T dwarfs to date. By following up several of the peculiar ultra cool dwarfs in our sample, we found a very young object (10Myrs), a number of dusty sources, and some that remain unexplained. Finally, we conducted a general search for rare objects in UKIDSS. Here we were interested in finding high redshift quasars, very cold white dwarfs or a yet unknown population by analysing objects with large χ2 values. While none of the above were found, we did find a moderate temperature H and He atmosphere white dwarf, a carbon star and some medium redshift quasars.
Room-temperature polariton condensates in all-dielectric microcavities.
Creators: name: Daskalakis, Konstantinos
Publisher: name: Imperial College London
Year: 2014

description: Cavity polaritons are quasiparticles formed when a photon con ned within a cavity interacts with an elementary excitation in a semiconductor that is called exciton. Under the right conditions, cavity polaritons form a macroscopic condensate in the ground state. This condensate decays through the cavity mirrors, thus providing coherent light-emission: a phenomenon termed polariton lasing. The threshold for polariton lasing can be signi cantly lower than that required for conventional lasing. Large exciton binding energies are an essential requirement to obtain polariton lasing at room temperature. Group III nitrides and ZnO are the only inorganic semiconductors possessing Wannier-Mott exciton binding energies above 25 meV, the room-temperature thermal energy. In contrast, Frenkel excitons in organic semiconductors possess binding energies of 1 eV and are thus highly stable at room temperature. This thesis consists of two parts. The first part concerns the fabrication and optical characterisation of samples consisting of an ultra-smooth GaN membrane encapsulated in an all-dielectric (SiO2/Ta2O5) distributed Bragg reflector (DBR) microcavity. By utilising the selective photo-electro-chemical (PEC) etching of an InGaN sacri cial layer, GaN membranes 200 nm thick are produced and introduced between DBRs. The second part is devoted to the demonstration of a room-temperature organic polariton condensate. The studied samples consist of a thermally evaporated 2,7-bis[9,9-di(4-methylphenyl)-fluoren-2-yl]-9,9-di(4-methylphenyl) fluorene (TDAF) thin film enclosed within an all-dielectric microcavity, consisting of SiO2 and Ta2O5 pairs. In both GaN and organic systems, the strong coupling for various detunings is demonstrated by performing angle-resolved reflectivity and photoluminescence (PL) measurements. On reaching threshold, the nonlinear increase in the PL is blueshifted with respect to low power emission, and is accompanied by a simultaneous reduction in the linewidth, marking the onset of polariton lasing at room-temperature. In the organic microcavities particularly, the condensate formed above threshold is linearly polarised and exhibits o -diagonal long-range order with a spatial coherence that is dependent on the pump shape. Moreover, the ambipolar electrical characteristics of this organic semiconductor and the high electron mobility of GaN suggest both materials as promising candidates for direct electrical injection.
Decentralized estimation and control for power systems
Creators: name: Singh, Abhinav Kumar
Publisher: name: Imperial College London
Year: 2014

description: This thesis presents a decentralized alternative to the centralized state-estimation and control technologies used in current power systems. Power systems span over vast geographical areas, and therefore require a robust and reliable communication network for centralized estimation and control. The supervisory control and data acquisition (SCADA) systems provide such a communication architecture and are currently employed for centralized estimation and control of power systems in a static manner. The SCADA systems operate at update rates which are not fast enough to provide appropriate estimation or control of transient or dynamic events occurring in power systems. Packet-switching based networked control system (NCS) is a faster alternative to SCADA systems, but it suffers from some other problems such as packet dropouts, random time delays and packet disordering. A stability analysis framework for NCS in power systems has been presented in the thesis considering these problems. Some other practical limitations and problems associated with real-time centralized estimation and control are computational bottlenecks, cyber threats and issues in acquiring system-wide parameters and measurements. The aforementioned problems can be solved by a decentralized methodology which only requires local parameters and measurements for estimation and control of a local unit in the system. The cumulative effect of control at all the units should be such that the global oscillations and instabilities in the power system are controlled. Such a decentralized methodology has been presented in the thesis. The method for decentralization is based on a new concept of `pseudo-inputs' in which some of measurements are treated as inputs. Unscented Kalman filtering (UKF) is applied on the decentralized system for dynamic state estimation (DSE). An extended linear quadratic regulator (ELQR) has been proposed for the optimal control of each local unit such that the whole power system is stabilized and all the oscillations are adequately damped. ELQR requires DSE as a prerequisite. The applicability of integrated system for dynamic estimation and control has been demonstrated on a model 16-machine 68-bus benchmark system.

description: Considering the theory of induced gravity coupled to matter fields, taking the $ϕ^6$ interaction potential model we evaluate the one-loop effective potential in a (3+1)dimensional Bianchi type-I spacetime. It is proved that the $ϕ^6$ theory can be regularised in (3+1)dimensional curved spacetime. We evaluate the finite temperature effective potential and study the temperature dependence of phase transitions. The nature of phase transitions in the early universe is clarified to be of first order. The effects of spacetime curvature and arbitrary field coupling on the phase transitions in the early universe are also discussed.

description: Cyclic peptides are a large class of natural compounds which attracted a great deal of attention, especially as potential amphi-ionophores. Herein, a theoretical study on the stability of new cystine-based tricyclopeptide (TCP) stereoisomers in achiral media in the presence of Li+, Na+, K+, F−, Cl−, and Br− ions was performed at the M06-2X/6-311++G(d,p) level of theory in both gas and aqueous phases. The nature of the intermolecular interaction between TCPs and ions were studied by natural bond orbital analysis (NBO) and the quantum theory of atoms in molecules (QTAIM) methods in gas phase. According to the size of the ions and configuration of TCPs, the location of ions (within or above the TCPs) and the types of formed intermolecular interactions are different. The results revealed that the free TCP7 and TCP8 enantiomers in gas phase and also TCP1 and TCP2 enantiomers in aqueous phase are the most stable structures among all TCPs. Moreover, the calculated energies of the optimised complexes containing the same ion show different stability order as compared to the free TCPs.

The Post-Shock Chemical Lifetimes of Outflow Tracers and a Possible New Mechanism to Produce Water Ice Mantles

description: We have used a coupled time-dependent chemical and dynamical model to investigate the lifetime of the chemical legacy left in the wake of C-type shocks. We concentrate this study on the chemistry of H2O and O2, two molecules which are predicted to have abundances that are significantly affected in shock-heated gas. Two models are presented: (1) a three-stage model of pre-shock, shocked, and post-shock gas; and (2) a Monte-Carlo cloud simulation where we explore the effects of stochastic shock activity on molecular gas over a cloud lifetime. In agreement with previous studies, we find that shock velocities in excess of 10 km s^-1 are required to convert all of the oxygen not locked in CO into H2O before the gas has an opportunity to cool. For pure gas-phase models the lifetime of the high water abundances, or ``H2O legacy'', in the post-shock gas is 4 - 7 x 10^5 years. Through the Monte Carlo cloud simulation we demonstrate that the time-average abundance of H2O is a sensitive function of the frequency of shocks. Thus we predict that the abundance of H2O and other known outflow tracers can be used to trace the history of shock activity in molecular gas. For gas-grain models we find that the abundance of water-ice on grain surfaces can be quite large and is comparable to that observed in molecular clouds. This offers a possible alternative method to create water mantles without resorting to grain surface chemistry: gas heating and chemical modification due to a C-type shock and subsequent depletion of the gas-phase species onto grain mantles.

description: Higher derivative scalar interactions can give rise to interesting cosmological scenarios. We present a complete classification of such operators that can yield sizeable effects without introducing ghosts and, at the same time, define an effective field theory robust under the inclusion of quantum corrections. A set of rules to power count consistently the coefficients of the resulting Lagrangian is provided by the presence of an approximate global symmetry. The interactions that we derive in this way contain a subset of the so-called Horndeski and beyond Horndeski theories. Our construction therefore provides a structurally robust context to study their phenomenology. Applications to dark energy/modified gravity and geodesically complete cosmologies are briefly discussed.

Effect of inhaled corticosteroids on viral and bacterial infection in chronic obstructive pulmonary disease
Creators: name: Singanayagam, Aran
Publisher: name: Imperial College London
Year: 2014

description: Rhinovirus (RV) infections trigger exacerbations of chronic obstructive pulmonary disease (COPD) exacerbations and may precipitate secondary bacterial infections. Inhaled corticosteroids (ICS) are used commonly in COPD but are relatively ineffective in the context of virus-induced exacerbations and may also increase the risk of pneumonia. We hypothesised that, in a mouse model, ICS would suppress anti-viral and anti-bacterial immune responses leading to alteration of the airway microbiota and secondary bacterial infection following RV-induced exacerbation of COPD. Despite extensive optimisation, we were unable to define a representative mouse model of the deficient anti-viral and anti-bacterial responses that are indicative of human COPD. For this reason, and because of difficulties in measuring the airway microbiota in mice, we employed models of primary RV1B and Streptococcus pneumoniae infection as surrogates for viral exacerbation and bacterial colonisation in COPD. Fluticasone propionate (FP) administration prior to RV1B infection suppressed innate and adaptive immune responses leading to impaired virus control, in a dose dependent manner. This effect was causally related to suppression of type I interferon (IFN) as administration of recombinant IFN-β reconstituted IFN-stimulated gene expression and restored virus control. FP suppressed RV-induced airway inflammation but led to enhanced airway mucin production, effects that were unaltered by recombinant IFN-β. FP administration also suppressed innate responses to S. pneumoniae including expression of anti-bacterial cytokines and cathelicidin-related anti-microbial peptide. High dose FP increased lung tissue bacterial loads with the opposite effect observed with lower dose FP despite similar anti-inflammatory effects. Our findings demonstrate beneficial anti-inflammatory effects of ICS during virus-induced COPD exacerbations but reveal some previously unrecognised detrimental effects including increased virus replication and enhanced mucin production. Additionally, we show that high dose ICS administration may increase bacterial loads and thus increase pneumonia risk but lower doses may conversely reduce bacterial loads and therefore could be safer in COPD.

description: We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e., impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the impurity-boson interaction. We show that the dipolar nature of the condensate and of the impurity results in anisotropic relaxation dynamics, in particular, anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench dynamics is strongly affected by the interplay between dipolar anisotropy and trap geometry. Our findings pave the way for simulating impurities in anisotropic media utilizing experiments with dipolar mixtures.

Analytical and numerical evidence are presented that the critical line forms a cusp at a finite gauge coupling, and the line of chiral transition runs past the tip of the cusp without touching the critical line. Implications on the continuum limit and the flavor dependence of chiral transition are discussed.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We discuss the O(4) invariant perturbation modes of cosmological instantons. These modes are spatially homogeneous in Lorentzian spacetime and thus not relevant to density perturbations. But their properties are important in establishing the meaning of the Euclidean path integral. If negative modes are present, the Euclidean path integral is not well defined, but may nevertheless be useful in an approximate description of the decay of an unstable state. When gravitational dynamics is included, counting negative modes requires a careful treatment of the conformal factor problem. We demonstrate that for an appropriate choice of coordinate on phase space, the second order Euclidean action is bounded below for normalized perturbations and has a finite number of negative modes. We prove that there is a negative mode for many gravitational instantons of the Hawking-Moss or Coleman-De Luccia type, and discuss the associated spectral flow. We also investigate Hawking-Turok constrained instantons, which occur in a generic inflationary model. Implementing the regularization and constraint proposed by Kirklin, Turok and Wiseman, we find that those instantons leading to substantial inflation do not possess negative modes. Using an alternate regularization and constraint motivated by reduction from five dimensions, we find a negative mode is present. These investigations shed new light on the suitability of Euclidean quantum gravity as a potential description of our universe.

description: Objectives Germany's 2019 Digital Healthcare Act (Digitale-Versorgung-Gesetz, or DVG) created a number of opportunities for the digital transformation of the healthcare delivery system. Key among these was the creation of a reimbursement pathway for patient-centered digital health applications (digitale Gesundheitsanwendungen, or DiGA). Worldwide, this is the first structured pathway for prescribable health applications at scale. As of October 10, 2023, 49 DiGA were listed in the official directory maintained by Germany's Federal Institute for Drugs and Medical Devices (BfArM); these are prescribable by physicians and psychotherapists and reimbursed by the German statutory health insurance system for all its 73 million beneficiaries. Looking ahead, a major challenge facing DiGA manufacturers will be the generation of the evidence required for ongoing price negotiations and reimbursement. Current health technology assessment (HTA) methods will need to be adapted for DiGA. Methods We describe the core issues that distinguish HTA in this setting: (i) explicit allowance for more flexible research designs, (ii) the nature of initial evidence generation, which can be delivered (in its final form) up to one year after becoming reimbursable, and (iii) the dynamic nature of both product development and product evaluation. We present the digital health applications in the German DiGA scheme as a case study and highlight the role of RWE in the successful evaluation of DiGA on an ongoing basis. Results When a DiGA is likely to be updated and assessed regularly, full-scale RCTs are infeasible; we therefore make the case for using real-world data and real-world evidence (RWE) for dynamic HTAs. Conclusions Continous evaluation using RWD is a regulatory innovation that can help improve the quality of DiGAs on the market.

description: Resonant elastic X-ray scattering (REXS) at the Eu $M_5$ edge reveals an antiferromagnetic structure in layered EuCd$_2$Sb$_2$ at temperatures below $T_\textrm{N}$ = 7.4 K with a magnetic propagation vector of $(0,0,1/2)$ and spins in the basal plane. Magneto-transport and REXS measurements with an in-plane magnetic field show that features in the magnetoresistance are correlated with changes in the magnetic structure induced by the field. Ab initio electronic structure calculations predict that the observed spin structure gives rise to a gapped Dirac point close to the Fermi level with a gap of $ΔE \sim$0.01 eV. The results of this study indicate that the Eu spins are coupled to conduction electron states near the Dirac point.

description: Bio-lubricants have demonstrated promising tribological and physical properties, suggesting their potential advantages in the lubrication of critical machinery components. This study investigates the impact of using blended individual and hybrid nanoadditives, such as graphene nanoplatelets, ZnO, and an ionic liquid (IL) of Trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl)phosphinate, on the rheological, tribological, and physical characteristics of rapeseed oil. A commercial cutting fluid (BLASER Vasco 6000) (VB 6000) is used for comparison. The results revealed a substantial improvement in viscosity index (VI) values for mixtures containing graphene nanoplatelets, reaching up to 150%, as compared to VB 6000. Regarding the tribological behavior, the friction coefficient achieved a reduction of up to 20% at room temperature (RT) and 26% at 60 °C for the hybrid containing all three nanoadditives (H3), outperforming the commercial fluid. Moreover, H3 demonstrated the most substantial reductions in wear volume (84%) and surface roughness (60%). The wettability of H3 benefited from the combined mechanisms of the applied nanoadditives; its application the contact angle decreased by 63%, revealing its outstanding spreadability. The results reveal the high potential of the H3 hybrid as a competitive and green metal working fluid that can replace hostile and toxic ones in industrial applications.

description: We demonstrate that in a class of the $U(1)'$ extension of the Standard Model (SM), under which all the Standard Model matter fields are uncharged and the additional neutral gauge boson $Z'$ couples to a set of heavy nonstandard fermions, dark matter (DM) production mediated by $Z'$ can proceed through the generation of generalized Chern-Simons (GCS) couplings. The origin of the GCS terms is intimately connected to the cancellation of gauge anomalies. We show that the DM production cross section triggered by GCS couplings is sufficient even for an intermediate scale $Z'$ . A large range of DM and Z masses is then allowed for reasonably high reheating temperature ($T_\rh \gtrsim 10^{10}~\text{GeV}$). This type of scenario opens up a new paradigm for unified models. We also study the UV completion of such effective field theory constructions, augmenting it by a heavy fermionic spectrum. The latter, when integrated out, generates the GCS-like terms and provides a new portal to the dark sector. The presence of a number of derivative couplings in the GCS-like operators induces a high temperature dependence to the DM production rate. The mechanism has novel consequences and leads to a new reheating dependence of the relic abundance.

As several novel compounds are available in powder form only, contactless methods, which also work on air sensitive samples, are higly desired. We present that the microwave cavity perturbation technique is a versatile tool to study conductivity in such systems. The examples include studies on semiconducting-metallic crossover in carbon nanotubes upon alkali doping, study of vortex motion in the K$_3$C$_{60}$ superconductor, and the characterization of various alkali atom doped phases of black phosphorus.

description: We investigate the angular correlation function, omega(theta), and third and fourth-order hierarchical moments of a survey with approx. 70000 faint galaxies detected on a total area 1.74 sq. deg. to a limit of R=23.5. The omega(theta) amplitudes and scaling with magnitude limit are most consistent with approximately stable clustering (epsilon=0). On the larger of our fields, the amplitude of omega(theta) is significantly higher at 2-5 arcsec separations than at >5 arcsec, indicating an excess of physically close galaxy pairs above the number expected from omega(theta) seen at larger scales. This is consistent with the number of interacting galaxy pairs seen locally combined with a merger/interaction rate evolving as (1+z)^m with m=2.01_{-0.69}^{+0.52}. We also estimate the hierarchical moments s_3 and s_4 from the galaxy counts-in-cells. For 18.5

description: In this work, parallel tempering has been used to explore the quantum chemical surface of SCN(−)(H2O)n system for n=1−8. The stretching frequencies and more specifically the shifts in –O–H stretching frequencies in this type of systems can serve as the fingerprint of a particular geometry. That is why, stretching frequencies of the water molecules have been evaluated and the changes in their values with successive addition of water molecules are also observed. The general trend of getting more and more red shifted peaks is also seen. Although, in some cases, the trend is slightly deviated, which is also mentioned and logical explanations have been given. Using this strategy several number of local structures along with the global one can also be located, as in a real experimental scenario, where finite temperature is present, any of the observable properties should not be guided by only the global minimum but should be an averaged out value contributed by the local structures along with the global one for a particular size of the cluster. Keeping this important fact in mind, the conformational populations of different isomers for a particular size have also been investigated for temperatures upto 300 K at 1 atm. pressure.
SU(3) Lattice Gauge Theory in the Fundamental--Adjoint Plane and Scaling Along the Wilson Axis

description: We present further evidence for the bulk nature of the phase transition line in the fundamental--adjoint action plane of SU(3) lattice gauge theory. Computing the string tension and some glueball masses along the thermal phase transition line of finite temperature systems with $N_t=4$, which was found to join onto the bulk transition line at its endpoint, we find that the ratio $\sqrtσ / T_c$ remains approximately constant. However, the mass of the $0^{++}$ glueball decreases as the endpoint of the bulk transition line is approached, while the other glueball masses appear unchanged. This is consistent with the notion that the bulk transition line ends in a critical endpoint, with the continuum limit there being a $ϕ^4$ theory with a diverging correlation length only in the $0^{++}$ channel. We comment on the implications for the scaling behavior along the fundamental or Wilson axis.

description: The ubiquity with which ‘so-called’ precedes critical iterations of ‘the New York School’ highlights the fundamental instability not only of this label, but also the concept of the poetic school more generally, yet bypasses much of the necessary work of destabilisation. This thesis is a critical examination of the ways in which the New York School has been conceived and constructed, and the marginalisations that occur as a result of such structures. Taking as its basis Griselda Pollock’s definition of the canon as ‘a discursive formation which constitutes the objects/texts it selects as the products of artistic mastery and, thereby, contributes to the legitimation of white masculinity’s exclusive identification with creativity and with Culture,’ it offers up a major revision to the way in which the New York School has been read, taught, and anthologised as a group of men. Since Maggie Nelson’s Women, The New York School, and Other True Abstractions (2007), there has been little development of her ideas, particularly in light of the rapidly changing landscape of contemporary poetry, and scant work has been done on the poets that she omits. Beginning with these theoretical problems, the thesis moves through six poets associated with the school — Barbara Guest, V.R. “Bunny” Lang, Alice Notley, Bernadette Mayer, Anne Waldman, and Eileen Myles — making use of a socio-biographical approach and substantial close reading in order to reassess, reframe, or discuss their work for the first time. This study is as much a queer project as it is a feminist project-of-recovery; it does not strive to find feminist/proto-feminist poets or poetics, but rather to disrupt received hierarchies, paradigms, and entrenched critical positions. It aims not to replicate hegemonic systems of criticism by assimilating women poets into the canon of the New York School, but to question the foundation of that canon, reformulating the school into a lens through which these poets can be usefully viewed, whilst simultaneously suggesting that they form a significant part of that lens.
Synthetic approaches to improving perylene diimide-based organic electronics
Creators: name: Oram, Stuart John
Publisher: name: Imperial College London
Year: 2013

description: This thesis deals with the family of small molecules known as perylene diimides, their synthesis, properties, and use in organic electronics. In particular it is focussed on the use of perylene diimides as small molecular organic semiconductors in organic photovoltaics and organic field-effect transistors. Here is reported the synthesis, characterisation, properties and device testing of a range of new perylene diimide materials, designed to have properties amenable to use as acceptors in organic photovoltaics. Also reported is a method for the kinetic resolution of dicyano substituted perylene diimides, an important sub-group commonly used in organic field-effect transistor applications, to obtain regioisomerically pure samples of the majority regioisomer from an otherwise inseparable mixture. The effect of this purification on the physical and device properties is reported. A new kind of perylene diimide material was discovered during the course of this work. The identification of the new material, determined by a combination of spectroscopy and modern computational chemistry techniques is reported, as well as properties relevant to the use of the new material in organic electronics. Finally, the synthesis, characterisation and properties of a new dicyano perylene diimide is reported, in order to investigate the use of targeted thermal treatment on organic field-effect transistor device performance.

description: Increasing evidence shows that immune-related genes (IRGs) play an important role in bariatric surgery (BS). We identified differentially expressed immune-related genes (DEIRGs) of adipose tissue after BS by analysing the two expression profiles of GEO (GSE59034 and GSE29409). Subsequently, enrichment analysis, GSEA and PPI networks were examined to identify the hub IRGs and related pathways. The performance of the signature was evaluated by area under the curve (AUC) of the receiver operating characteristic (ROC). CIBERSORT algorithm was used to evaluate the relative abundance of infiltrated immune cells.42 DEIRGs were found between the GSE59034 and GSE29409 datasets. The AUC of the signature was 0.904 and 0.865 in the GSE58979 and GSE48452, respectively. Interestingly, the signature also showed good performance in diagnosing non-alcoholic fatty liver disease (NAFLD) (AUC was 0.834 and 0.800, respectively). The number of neutrophils, macrophages M2, macrophages M0 and dendritic cells activated decreased significantly. After BS, the infiltration of T cells regulatory, monocytes, mast cells resting and plasma cells in adipose tissue increased. The novel proposed IRGs signature reveals the underlying immune mechanism of BS and is a promising biomarker for distinguishing the severity of NAFLD. This will provide new insights into strategies for treating obesity and NAFLD.
Novel in vivo biosensors for monitoring of mammalian cell cultures
Creators: name: Goers, Lisa
Publisher: name: Imperial College London
Year: 2014

description: Mammalian cell cultures are used for production of biopharmaceuticals, e.g. monoclonal antibodies. Only mammalian hybridoma cells contain the pathways for antibody production, but due to their multicellular origin the cells have complex nutrient requirements. Cell growth and antibody production are limited by supply of essential nutrients such as glutamine and accumulation of toxic waste products such as lactate. Many attempts have been made at tackling these challenges, e.g. by optimising growth media to keep metabolite concentrations at optimal levels. These approaches have been hampered by our ability to monitor relevant cell culture parameters such as metabolite concentration dynamics in real time. The aim of this study is to develop a solution to this problem using a synthetic biology approach. Whole-cell bacterial biosensors for important culture parameters, glutamine, leucine, alanine and lactate, were designed, built and characterised. The biosensors were designed from natural metabolite-sensing systems, specifically the Escherichia coli Ntr regulon, Lrp regulon and lldPRD operon and the Bacillus subtilis GlnK-GlnL system. Characterisation of the biosensors in defined medium using known lactate concentrations was followed by validation in mammalian cell culture media and using cell culture samples. A lactate sensor based on the lldPRD operon showed a reliable lactate-response during initial characterisation and was chosen to determine lactate concentrations in cell culture samples in parallel with lactate analysis using a bioprofiler. Generally, the lactate concentrations from the two methods showed a good match. Data points where the results differed showed that there are some sources of error in the usage of the biosensor that could be addressed in future. The results of this study also highlight the many challenges of applying synthetic biology constructs to complex industrial contexts. The biosensors presented in this study are more generally applicable in any experimental context that requires sensing of metabolites.
