Construction of a platform based on biocompatible near-infrared Ag <sub>2</sub> S quantum dots for detection of copper ions in real samples and cellular environments The persistent challenge of real-time copper analysis in complex biological matrices underscores the urgent need for advanced sensing paradigms. To overcome the conventional trade-offs among response speed, detection accuracy, and biocompatibility, we have developed a near-infrared Ag 2 S quantum dots (QDs) platform through one-pot microwave synthesis. The as-prepared Ag₂S QDs exhibit remarkable water solubility, excellent dispersibility, and optical properties. Benefiting from these features, the sensing system enables rapid Cu 2 ⁺ detection with a response time of only 30 s, greatly improving analytical efficiency. Moreover, the near-infrared emission and large Stokes shift (290 nm) characteristics effectively reduce background scattering and autofluorescence interference, facilitating highly sensitive quantitative detection of Cu 2+ with a limit of detection (LOD) of 21 nM. More importantly, this strategy demonstrates excellent selectivity and biocompatibility, successfully applied for the detection and visualization of Cu 2+ in real samples and living cells. Overall, this strategy offers a powerful and practical approach for Cu 2 ⁺ monitoring, showing great potential in environmental surveillance and Cu 2+ -related disease research.

Features and mechanism of localized enzyme-assisted self-assembly of peptides from unilamellar vesicles Localized enzyme-assisted self-assembly (LEASA) has emerged as a powerful tool to generate peptide nanofibers from and within bacteria or cancer cell lines. This approach has led to promising developments in medical imaging, antimicrobial treatments and cancer therapies. Despite these achievements, the features of self-assembly processes localized near the plasma cell membranes and induced by enzymes are not easy to study since biological media compositions are complex and vary over time. From model systems based on giant and small unilamellar vesicles (GUV and SUV respectively) displaying phosphatases at the outer edge of their phospholipid's membrane, we study the self-assembly of peptides triggered by an enzymatic dephosphorylation. Peptide nanofibers, generated in the close vicinity of GUVs, adsorb all around the membrane where enzymes are located. This process induces the formation of a transient permeability through the membrane without destroying the vesicles, as observed by confocal laser scanning microscopy (CLSM). A cryo-transmission electron microscopy (cryo-TEM) monitoring over time highlights a lag-time before the formation of nano-aggregates located all around SUVs, followed by a rapid formation of short nanofibers near or directly from vesicles. Thanks to the presence of enzymes located on the surface of the vesicles, the micrometer-long nanofibers both adhere and exert such a mechanical force on the spherical shape of vesicles that they deform them. Finally, based on classical molecular dynamics simulations, we propose a mechanism that accounts for all our experimental observations, rationalizing the LEASA process induced on the surface of phospholipid bilayers containing phosphatases.

Mesoporous silica nanoparticles--based functional platforms for breast cancer therapy: technological advancements Mesoporous silica nanoparticles (MSNs) offer remarkable opportunities for the loading and delivery of drugs and other small molecules due to their large specific surface area, tunable mesoporous pore size, ease of modification, and excellent biocompatibility. The active silica hydroxyl groups (Si-OH) on the surface provide a good basis for a variety of modification and functionalization strategies, and thus MSNs show great potential in drug delivery systems, especially in studies involving the loading, transport, and release of anticancer drugs, particularly in the field of oncology therapeutics. The current review highlights MSNs as promising platforms for breast cancer therapy, with a special focus on the diverse applications of MSNs in breast cancer therapy, which are related to a wide range of applications with different structures and designs, functionalization strategies, prevalent synthesis methods, and potential clinical uses. Afterwards, we review targeted MSNs for enhancing precision medicine and therapeutic efficacy, and then focus on specific applications of MSNs in breast cancer therapy and various stimulus-responsive surface modifications, with specific applications including drug delivery, photodynamic therapy, photothermal therapy, combined therapeutic approaches, gene therapy, and immunotherapy. In addition, the challenges of MSNs in breast cancer and their future prospects are discussed.

Application Of Voltammetry In The Assessment Of Some Metal Ions In Drinking Water Samples In Al-Baha City, Saudi Arabia Objectives Metal ions such as, Cd (II), Pb (II), Cu (II), and Zn (II) in drinking water samples were investigated by employing differential pulse anodic stripping voltammetry (DPASV) at carbon paste electrode (CPE). Materials and methods The investigated samples were collected from Al-Baha city, KSA. The samples were taken from eight sampling regions. The effects of various factors were examined. The lower limits of the investigated metal ions at 150s deposition time (n= 5) are 0.314 µg/L (r = 0.9899) for zinc(II), 0.368 µg/L (r = 0.8992) for cadmium(II), 1.28 µg/L (r = 0.9899) for lead(II) and 0.118 µg/L (r = 0.9998) for copper(II), respectively. Results The assessments of the investigated metal ions in drinking water were in the range for Zn (II) (0.42–68.5 µg/L with SD= 0.13–0.96, n= 5), Cd(II) (0.29–0.87 µg/L with SD = 0.03–1.02, n= 5), Pb(II) (1.5–22.35 µg/L with SD = 0.08–0.73, n = 5), and for Cu(II) (0.58–2.58 µg/L with SD = 0.02–0.85, n= 5), respectively. The resulting data were compared with those estimated by the atomic absorption spectrophotometric technique. The interfering and the storage conditions of the samples were examined. Conclusion The determined concentrations were within internationally accepted drinking water standards, indicating the suitability and the instantaneous estimation of the proposed method for trace metal analysis in water samples.

Impact of hydrogen incorporation on electronic and magnetic structure of X2CrNi18-9 stainless steel Hydrogen absorption significantly alters the mechanical properties of steel. However, absorbed hydrogen also influences its electronic and magneto-structural properties, helping to interpret how hydrogen is incorporated. This study therefore investigates the influence of hydrogen incorporation on the electronic and magneto-structural properties of X2CrNi18-9 stainless steel in different microstructural states. Microstructural characterization included analytic electron microscopy mapping, X-ray diffraction and thermodynamic stability maps to evaluate grain size, dislocation density and chemical homogeneity. The electronic properties were characterized using the Seebeck coefficient, while the magneto-structural properties were investigated using diffuse neutron scattering and small-angle neutron scattering (SANS). Hydrogen incorporation showed clear changes in the Seebeck coefficients. Magnetic SANS in conjunction with diffuse neutron scattering indicates the existence of nanoscale inhomogeneities with the same fcc structure as the bulk, but with correlation lengths of a few nanometres. The size of these inhomogeneities increased with hydrogen incorporation, suggesting that hydrogen preferentially accumulates in their vicinity. However, no direct correlation between the electronic and magneto-structural properties and the dislocation density could be demonstrated. We suggest that studies such as these will lead in the medium term to the development of guidelines for material design to make steels more resistant to hydrogen.

Ab-Initio Examination of Ni’s Stability, Electrical, Optical, and Magnetic Properties with GGA and GGA+U We determined the electronic structure, optical characteristics, magnetic moments, and stability of the face-centered cubic (fcc) and body-centered cubic (bcc) for nickel (Ni) in its ferromagnetic (FM), anti-ferromagnetic (AFM), and non-magnetic (NM) states. Using density functional theory (DFT) as a framework with the WIEN2k program, the intended result was obtained using the generalized gradient approximation (GGA) and GGA+U in the full-potential linearized method of augmented plane waves (FP-LAPW). The magnetic moments exhibit periodic increases when significant correlations are considered. According to Iota’s observations, the Density of States (DOS) differs dramatically with FM states but not with NM or AFM states, which is consistent with Iota’s observations. We report the behavior of the interband dielectric function ε(ω) , refractive index n(ω) , energy-loss spectrum L(ω) , optical absorption σ(ω) , reflectivity R(ω) , and absorption coefficient α(ω) . Our findings are strikingly consistent with earlier theoretical and experimental studies.

Structural, Photoluminescence and Colorific Properties of Sm3+ doped ZnMoO4 Phosphors for Warm White LEDs Zinc molybdates (ZnMoO4) phosphors activated with different samarium (Sm3+) amounts (0.5, 1.0, 1.5 and 2.0 mol%) were synthesised using a low temperature initiated citrate gel combustion process. The crystal structure of ZnMoO4:Sm3+ phosphors were analysed by XRD and their size was determined to be approximately 20 nm by the Scherrer equation. The FTIR spectral studies confirmed the presence of the distinct functional groups in the prepared phosphors. When the n-UV was excited to 402 nm, four emission maxima (PL) were detected at 567, 602, 649 and 708 nm. These were linked to the Sm3+ ion transitions: 4G5/2→6H5/2 (yellow), 6H7/2 (orange), 6H9/2 (reddish orange) and 6H11/2 (red). Dexter and Shulman’s theory studied the multipolar interaction that causes photoluminescence (PL) quenching via dipole-dipole type interaction in the present ZnMoO4:Sm3+ phosphors. The double-exponential function was used to fit the decay curves of the prepared phosphors and their lifetimes were found to be 1.23, 1.19, 1.11 and 1.09 ms. The colorimetric characteristics, which span the values (x, y) of 0.60 and 0.40, the colour purity of 96% and the colour temperatures below 2000 K, indicate that the fluorescent materials ZnMoO4:Sm3+ have great potential for use in light-emitting diodes (warm-LEDs).

Multifunctional Sr-doped Co–Mn Spinel Nanochromites for Antimicrobial and DNA Interaction Applications A series of Co0.25Sr0.50MnxCr2-xO4 nanochromite samples, where x ranges from 0.05, 0.15, 0.25, were prepared by the citrate gel-auto combustion technique. The structural, optical and biological activities of the prepared samples were investigated. A single-phase cubic spinel structure was confirmed by XRD with Fd3m space group. The crystalline size was found to be in the range of 5.80 to 19.86 nm, calculated using Scherrer formula. FESEM images revealed a spherical and agglomerated structure and the presence of Mn, Co, Sr, Cr and O was confirmed by the EDS spectrum. The presence of M–O bond linkage in tetrahedral and octahedral bands was in the FTIR spectrum. The band gap energy of the samples ranged from 1.93 eV and 1.52 eV calculated using Tauc plots. The biological studies were investigated through antibacterial and antifungal activity using the pour plate method. The synthesized nanospinels exhibited significant antifungal activity against Candida and Aspergillus, with clear zones of inhibition (~12 mm) and low MIC values (as low as 25 µL), demonstrating strong dose-dependent efficacy. Furthermore, the prepared nanochromites exhibited partial ctDNA cleavage and moderate DNA binding affinity (Kb ~104 M–1), indicating weak-to-moderate groove/electrostatic interactions. While antibacterial activity was minimal, the materials demonstrated pronounced antifungal efficacy against Candida and Aspergillus, with ~12 mm inhibition zones and low MIC values (&gt; 25 µL), confirming composition-dependent and dose-responsive antifungal performance.

Comparative antibacterial and anti-virulence effects of silver ions from electrolysis, silver nanoparticles, and silver nitrate against Pseudomonas aeruginosa and Staphylococcus aureus The biological activity of silver-based antimicrobial agents is strongly influenced by the source and generation method of silver ions (Ag⁺); however, a direct comparison of their efficacy from different sources has not been previously reported. In this study, we systematically compared the antibacterial and anti-virulence effects of Ag⁺ derived from three sources: direct current (DC) electrolysis, silver nanoparticles (Ag-NPs), and silver nitrate (AgNO₃), standardized to 400 ppm. Electrolyzed Ag⁺ exhibited the strongest antibacterial effect, reducing viable counts of Pseudomonas aeruginosa and Staphylococcus aureus by 91.06% and 71.10%, respectively. It also caused substantial membrane disruption, reduced motility, and increased cellular leakage, as confirmed by SEM imaging, DNA and K⁺ ion leakage, and extracellular protein release. Furthermore, electrolyzed Ag⁺ most effectively suppressed key virulence factors, including biofilm formation, pigment production (pyocyanin, staphyloxanthin), and the activities of protease, esterase, and hemolysin. Despite identical Ag⁺ concentrations, the biological activity varied significantly with ion source, underscoring the importance of the delivery mechanism. These findings highlight the superior efficacy of electrolyzed Ag⁺ and support its potential application in clinical, environmental, and industrial antimicrobial strategies.

Literature Review on the Study of Colloidal Systems in Condensed Matter Physics Materials with particles in liquid form provide important research areas in the study of matter and show considerable development over recent decades. These systems contain solid elements distributed within liquid environments, and the particles range from very small to larger scales. The behavior that these systems show and the properties that can be changed make them a main focus for investigation. Studies over recent decades examine basic processes such as the formation of ordered structures, the initial appearance of solid forms, transition to disordered states, and imperfections in structure. The findings from this work develop and strengthen the understanding of changes between different phases. Research that examines these systems, which allow direct observation, reveals patterns in the movement of particles in flat arrangements at small scales. The features that these systems possess make it possible to understand how particles organize without external direction. Control of particle form and arrangement creates different approaches for directing the process of organization. This work presents recent findings in the study of these materials in the field of examining matter, with a focus on their arrangement, movement patterns, and uses, and describes new directions for investigation and discusses possible future issues.

Molecular dynamics insights into temperature effects on polyurethane-aggregate adhesion: comparative analysis of SiO2 and CaCO3 In this study, molecular dynamics was used to investigate the adhesion properties between polyurethane and aggregate and to reveal the adhesion mechanism between polyurethane and aggregate. The influence of the aggregate type and temperature on the polyurethane-aggregate adhesion properties was investigated. The polyurethane-aggregate adhesion properties were evaluated using interaction energy, interaction energy fraction, adhesion work, radial distribution function, fractional free volume and relative concentration distribution. The adhesion properties between polyurethane-SiO 2 aggregate have temperature sensitivity, while temperature hardly affects the adhesion between polyurethane-CaCO 3 aggregate. Van der Waals forces and hydrogen bonding are the dominant factors affecting the adhesion properties of polyurethane-SiO 2 aggregates, while electrostatic energy is the main contributor to the adhesion properties of polyurethane-CaCO 3 aggregates. The temperature increased reduced the molecular gap between the polyurethane and SiO 2 and increased the interaction force between the polyurethane molecules and SiO 2 .
