Summary: The UV-vis absorption and fluorescence spectra of a series of merocyanines with different heterocyclic donor and carbonyl-comprising acceptor groups were studied at 77K in frozen ethanol. The electronic structure of the molecules became more dipolar in the frozen solvent matrix compared to the liquid solvent, leading to spectral effects depending on the donor-acceptor abilities of the terminal groups. The fluorescence bands shifted hypsochromically at cryotemperature and were closely mirror-like to the absorption bands, indicating inhibited solvent rearrangement in the frozen matrix.

Summary: Push-pull fluorophores containing a 2,2'-bipyridine acceptor with carbazole/fluorene groups exhibited good fluorescence performance with high fluorescence quantum yields and large Stokes shifts. The solvatochromic method was successfully applied to evaluate their hyperpolarizability coefficients. Two-photon emission cross sections were measured, confirming the greatest charge separation in carbazole-substituted isomers. The fluorene-containing fluorophores showed a planarized ICT process and can be used as environment polarity-sensitive fluorescent dyes and probes for detecting structural changes in proteins/biomolecular interactions and optical switches.

Summary: In order to improve the performance of theoretical UV-Vis spectra predictions, a study of solvatochromic properties of ten azo pyridone dyes was conducted. By applying the concept of linear solvation energy relationships using Kamlet-Taft and Catalan models, the intermolecular solvent-solute interactions were quantitatively estimated. Theoretical UV-Vis spectra were calculated using four TD-DFT methods in nine different solvents, and new polylinear equations for more accurate prediction of UV-Vis maxima were developed.

Summary: Novel poly(methacrylic acid)/gelatin (PMAG) interpenetrating networks with nanostructured particles of hydroxyapatite (HA) as reinforcement have been synthesized. The introduction of HA significantly improves the mechanical properties, while slightly reducing the swelling ability, pH sensibility, and porosity. Increasing the HA/polymer ratio to 40% enhances the compressive strength from 29.83 to 68.16 kPa. The drug release kinetics of hydrophilic ciprofloxacin and hydrophobic oxaprozin demonstrate different behaviors under simulated physiological conditions. In vitro antimicrobial testing shows bactericidal and fungicidal activity of the drug-loaded hydrogels against E. coli, S. aureus, and C. albicans.

The changes in Eu3+ local surroundings due to temperature increase modified the intensity and emission spectra, and the intensity ratio of Eu3+ 5D0 -> 7F2 to 5D0 -> 7F1 emissions served as a highly-sensitive indicator of the highest temperature experienced by the nanocrystals. The proposed ratiometric readout strategy enhanced the accuracy of thermal history analysis.

In silico predictions and experimental results showed that most compounds had good skin permeability, but two compounds with carboxylic groups had limited permeation at pH 7.4. The study found a significant association between in silico predicted logKp values and experimental permeability, indicating the importance of lipophilicity in passive permeation through hydrophobic barriers.

Summary: Lifetime-based luminescence thermometry enables accurate deep-tissue monitoring of temperature changes, but short lifetimes and poor brightness limit its performance. A solution to these limitations is the design and optimization of luminescent nanothermometers co-doped with transition metal and lanthanide ions, which exhibit strong near-infrared emission and long temperature-dependent photoluminescence lifetime. These nanothermometers, combined with a custom-made instrument, allow for obtaining 2D thermal maps for deep-tissue thermal mapping. This study provides foundations for the deployment of lifetime-based thermometry for accurate deep-tissue temperature monitoring.

Summary: We present a hydrothermal synthesis method for ultrasmall Yb3+/Tm3+ co-doped Sr2LaF7 (SLF) upconversion phosphors. By varying the concentrations of Yb3+ (x = 10, 15, 20, and 25 mol%) and Tm3+ (y = 0.75, 1, 2, and 3 mol%), the emissions in the near IR spectral range were analyzed. Structural analysis revealed that Yb3+ and Tm3+ occupy the La3+ sites in the SLF host. The addition of Yb3+/Tm3+ ions significantly affected the lattice constant, particle size, and PL emission properties of the synthesized SLF nanophosphor. The optimal dopant concentrations for upconversion luminescence were found to be 20 mol% Yb3+ and 1 mol% Tm3+ with EDTA as the chelating agent. Strong upconversion emission of Tm3+ ions around 800 nm was achieved under 980 nm light excitation. The study suggests potential applications of ultrasmall Yb3+/Tm3+ co-doped SLF phosphors in fluorescent labels for bioimaging and security.

Summary: Colloidal stabilization is crucial for the preparation of magnetic nanoparticles for biomedical applications. In this study, tannic acid was used as a coating for barium hexaferrite nanoplatelets (BSHF NPLs) to achieve stability in aqueous media. The coated BSHF NPLs were characterized and their magnetic properties were measured. The stable colloids were tested in biological media, and the antimicrobial properties were examined. To enhance antimicrobial activity, tannic acid was used as a platform for the in-situ production of silver on BSHF NPLs. The hybrid material exhibited magnetic properties and excellent antimicrobial activity against Escherichia coli and Staphylococcus aureus.

Summary: This study explores the underestimated role of molecular mimicry in the etiology and progression of type 1 diabetes (T1D). The comprehensive immunoinformatics analysis of T1D-specific T-cell epitopes across bacterial, fungal, and viral proteomes reveals potential bacterial triggers and heat-shock proteins as the most potent autoantigens for T-cell priming via molecular mimicry. The re-analysis of T1D gut microbiota datasets suggests that the pre-T1D stage shows significant dysbiosis, indicating the importance of molecular mimicry in T1D.
