Orientation Ordering of Nanoparticle Ag/Co Cores Controlled by Electric and Magnetic Fields
Authors: Gmucová Katarína , Weis Martin , Nádaždy Vojtech , Majková Eva 
Published: April 2008

AbstractThe effect of electric and magnetic fields on the sandwich structure Pt/hydrogenated amorphous silicon (a‐Si:H)/stearic acid monolayer/Langmuir–Blodgett film of Ag/Co nanoparticles encapsulated in an organic envelope is studied. This structure is used as a working electrode in an electrochemical cell filled with NaCl solution (1 mM) and equipped with an Ag/AgCl reference electrode. Reversible changes in voltammograms are observed due to treatments (negative or positive bias voltage and simultaneous laser irradiation) applied to the designed structure before measurements. As an explanation of the observed phenomena we suggest that both the Co‐up and Ag‐up (on the a‐Si:H surface) orientation orderings of nanoparticle Ag/Co cores are repeatedly reached. The role of the photovoltaic material (a‐Si:H) in the observed behavior is explained. Voltammetric measurements with an applied magnetic field support our idea about the orientation ordering of nanoparticle cores.
Supplementation with high‐oleic sunflower oil and α‐tocopheryl acetate: Effects on pork meat lipids
Authors: Boselli Emanuele , Pacetti Deborah , Lucci Paolo , Di Lecce Giuseppe , Frega Natale G. 
Published: April 2008

AbstractThe effects of a dietary administration of high‐oleic sunflower oil (O) (about 85% oleic acid) to pigs, either or not in combination with α‐tocopheryl acetate (E), were assessed with regard to the composition of the triacylglycerols, phospholipids and the level of vitamin E in Italian heavy pork meat. Four different diets with the same lysine/calorie ratio (control; 3% O; 250 mg/kg E; 3% O + 250 mg/kg E) were administered to castrated males and intact females until slaughtering (160–170 kg). The lipids of the loin (Longissimus lumborum) were characterized. The administration of the diets rich in O with or without E led to an increase in the content of triacylglycerols containing oleic acid and a decrease of those containing linoleic and saturated acids, both in males and in females. The level of unsaturation of the phospholipid molecular species was less affected than that of the triacylglycerols. However, the content of phosphatidylcholine increased, whereas the content of phosphatidylserine decreased in the meat obtained with the diets O and OE, with respect to the corresponding controls (C and E). The level of free vitamin E doubled.
Covalent Sidewall Functionalization of SWNTs by Nucleophilic Addition of Lithium Amides
Authors: Syrgiannis Zois , Hauke Frank , Röhrl Jonas , Hundhausen Martin , Graupner Ralf , Elemes Yiannis , Hirsch Andreas 
Published: April 2008

AbstractThe synthesis and characterization of sidewall‐functionalized SWNT derivatives (nPrNH)n‐SWNTs containing n‐propylamine addends is reported. The nucleophilic addition of in situ generated lithium n‐propylamide to the sidewall of SWNTs and the subsequent reoxidation of charged intermediates of the type (nPrNH)n‐SWNTn– leads to carbon nanotube derivatives with covalently attached amino groups. Based on the reaction sequence, a homogeneous dispersion of the carbon nanotube material is achieved as a result of the electrostatic repulsion of negatively charged intermediates. The solubility of the resulting propylamine‐functionalized (nPrNH)n‐SWNT material in organic solvents is drastically increased. The functionalized tubes were characterized in detail by Raman spectroscopy, thermogravimetric analysis (TGA/MS), X‐ray photoelectron spectroscopy (XPS) and UV/Vis/NIR spectroscopy.

Stereocomplementary Asymmetric Reduction of Bulky–Bulky Ketones by Biocatalytic Hydrogen Transfer
Authors: Lavandera Iván , Oberdorfer Gustav , Gross Johannes , de Wildeman Stefaan , Kroutil Wolfgang 
Published: April 2008

AbstractBiocatalysts suitable for the reduction of ketones bearing two sterically demanding substituents (bulky–bulky ketones) at elevated substrate concentration (10 g L–1) were identified. The biocatalysts can be employed in a substrate‐coupled approach; thus, a simple alcohol such as ethanol or 2‐propanol serves as a hydrogen donor. Both enantiomers are accessible by using either Rhodococcus ruber DSM 44541 and ethanol or Ralstonia sp. DSM 6428 and Sphingobium yanoikuyae DSM 6900 and ethanol or 2‐propanol as the hydrogen source. For Rhodococcus ruber DSM 44541, it was found that bulky–bulky ketones were only transformed when ethanol was used as a hydrogen source, whereas no conversion was observed when 2‐propanol was employed. From the substrate spectrum, as well as from the cosubstrate preference, it became clear that a different alcohol dehydrogenase than the previously described ADH‐“A” is active in the presence of ethanol in Rhodococcus ruber.(© Wiley‐VCH Verlag GmbH & Co.

Determining under‐ and oversampling of individual particle distributions in microfluidic electrophoresis with orthogonal laser‐induced fluorescence detection
Authors: Whiting Christofer E. , Dua Rajat A. , Duffy Ciarán F. , Arriaga Edgar A. 
Published: April 2008

AbstractThis report investigates the effects of sample size on the separation and analysis of individual biological particles using microfluidic devices equipped with an orthogonal LIF detector. A detection limit of 17 ± 1 molecules of fluorophore is obtained using this orthogonal LIF detector under a constant flow of fluorescein, which is a significant improvement over epifluorescence, the most common LIF detection scheme used with microfluidic devices. Mitochondria from rat liver tissue and cultured 143B osteosarcoma cells are used as model biological particles. Quantile–quantile (q–q) plots were used to investigate changes in the distributions. When the number of detected mitochondrial events became too large (>72 for rat liver and >98 for 143B mitochondria), oversampling occurs. Statistical overlap theory is used to suggest that the cause of oversampling is that separation power of the microfluidic device presented is not enough to adequately separate large numbers of individual mitochondrial events. Fortunately, q–q plots make it possible to identify and exclude these distributions from data analysis. Additionally, when the number of detected events became too small (<55 for rat liver and <81 for 143B mitochondria) there were not enough events to obtain a statistically relevant mobility distribution, but these distributions can be combined to obtain a statistically relevant electrophoretic mobility distribution.
Fabrication, modification, and application of poly(methyl methacrylate) microfluidic chips
Authors: Chen Yun , Zhang Luyan , Chen Gang 
Published: April 2008

AbstractPoly(methyl methacrylate) (PMMA) is particularly useful for microfluidic chips with the features of low price, excellent optic transparency, attractive mechanical and chemical properties, ease of fabrication and modification, biocompatibility, etc. During the past decade, significant progress in the PMMA microfluidic chips has occurred. This review, which contains 120 references, summarizes the recent advances and the key strategies in the fabrication, modification, and application of PMMA microfluidic chips. It is expected that PMMA microchips should find a wide range of applications and will lead to the creation of truly disposable microfluidic devices.

Published: April 2008

AbstractA simple and sensitive on‐chip preconcentration, separation, and electrochemical detection (ED) method for the electrophoretic analysis of food dyes was developed. The microchip comprised of three parallel channels: the first two are for the field‐amplified sample stacking (FASS) and subsequent field‐amplified sample injection (FASI) steps, while the third one is for the micellar EKC with ED (MEKC‐ED) step. The food dyes were initially extracted from real samples by employing a method that was simpler, easier, and faster compared with a standard method. The extraction of the samples was characterized by UV–Vis and electrochemical experiments. The chronoamperometric detection was performed with a glassy carbon electrode coupled horizontally with the microchip at the separation channel exit. Experimental parameters affecting the analytical performance of the method were assessed and optimized. The sensitivity of the method was improved by ∼10 800‐fold when compared with a conventional MEKC‐ED analysis. Reproducible response was observed during multiple injections of samples with an RSD of <7.2% (n = 5). The calibration plots were linear (r2 = 0.998) within the range of 1.0 nM–1.0 μM for all food dyes. LODs were estimated between 1.0 and 5.0 nM, based on S/N = 3, for food dyes. The applicability of the method for the analysis of food dyes in real sample was demonstrated.
Electrochemical techniques for microfluidic applications

Published: April 2008

AbstractElectrochemical principles provide key techniques to promote the construction of bio/chemical microsystems of the next generation. There is a wealth of technology for the microfabrication of bio/chemical sensors. In addition, microfluidic transport in a network of flow channels, pH regulation, and automatic switching can be realized by electrochemical principles. Since the basic components of the devices are electrode patterns, the integration of different components is easily achieved. With these techniques, bio/chemical assays that require the exchange of solutions can be conducted on a chip. Furthermore, autonomous microanalysis systems that can carry out necessary procedures are beginning to be realized. In this article, techniques developed in our group will be comprehensively introduced.
A high‐discernment microflow cytometer with microweir structure
Authors: Fu Lung‐Ming , Tsai Chien‐Hsiung , Lin Che‐Hsin 
Published: April 2008

AbstractUsing a simple and reliable isotropic wet etching process, we fabricated a microflow cytometer in which cells/particles are concentrated in the center of the sample stream using a 2‐D hydrodynamic focusing technique and an microweir structure. Having focused the cells/particles, they are detected and counted using a LIF method. The experimental and numerical results confirm the effectiveness of the hydrodynamic sheath flows in squeezing the cells/particles into a narrow stream in the horizontal X–Y plane. Furthermore, it is shown numerically that the microweir structure results in the separation of the cells/particles in the vertical X–Z plane such that they pass through the detection region in a sequential fashion and can therefore be counted with a high degree of precision. The experimental results obtained using fluorescent polystyrene beads with diameters of 5 and 10 μm, respectively, confirm the suitability of the proposed device for microfluidic applications requiring the high‐precision counting of particles or cells within a sample flow.
