Summary: Solvent composition plays a crucial role in the synthesis of metal complex materials. In this study, a unique Schiff base Cu complex catalyst was designed and the effect of adding H2O during the synthesis process on the catalyst's catalytic performance was investigated. The results showed that adding a small amount of H2O significantly enhanced the catalyst's catalytic ability and improved the removal of the pollutant Methyl-paraben.

Summary: The selective epoxidation of limonene using dioxomolybdenum((VI)) complexes anchored on TiO(2) nanotubes was studied, showing the influence of ligands on stereoselectivity. Complexes with non-chiral ligands exhibited moderate diastereoselectivity towards the cis-isomer of limonene. Contrary to this, the complex with Schiff base as chiral ligand showed an increase in diastereoisomeric excess, indicating an asymmetric double induction.

Summary: Allylic alcohol epoxidation and dehydrogenation reactivity exhibit distinct behavior when VO(acac)(2) is used in solution or anchored in a metal-organic framework (MOF). The chemical mechanism is dependent on the electronic profile of alkene substituents when the vanadyl complex is used in the homogeneous phase. However, the confinement effects of MOF channels enable control over the chemoselectivity towards the dehydrogenation product.

Summary: The study focused on the effects of solvent polarity on the absorption and fluorescence spectral properties of three new fluorescent o-hydroxyaryl Schiff base derivatives. Different solvents with varying polarities were used to investigate specific and non-specific solute-solvent interactions. It was found that Schiff base compounds are more polar in the excited state compared to the ground state.

Summary: The study presents a simple, low-cost strategy for the preparation of CuS-BSA nanoparticles loaded with lysozyme as an antibacterial drug model. The CuS-BSA/lysozyme nanocomposite showed effective bacterial elimination of both Gram-positive and Gram-negative bacteria through photothermal and photodynamic activities, enhancing the antibiotic action of the enzyme. The biocompatibility of the CuS-BSA NPs makes them a promising drug carrier for overcoming the limitations of traditional antibiotic therapy.

Summary: Dermaseptin B2 (DRS-B2) is an antimicrobial peptide secreted by the Amazonian tree frog, Phyllomedusa bicolor. This study demonstrates that adsorption of DRS-B2 onto alginate nanoparticles enhances its antibacterial activity, particularly against colistin-resistant strains of Escherichia coli. The addition of lactic acid or menthol further enhances the antibacterial activity of this new formulation. Safety and stability tests conducted on human erythrocytes and eukaryotic cell lines indicate the potential of these formulations as alternatives to antibiotics for treating Gram-negative bacterial infections such as E. coli.

Summary: The ongoing pandemic of COVID-19 highlights the importance of diagnostic testing in outbreak control. Current diagnosis methods largely rely on RT-PCR, but there have been proposals to use SPR-based sensing platforms to detect the presence of SARS-CoV-2 viral particles. This review provides an overview of the state-of-the-art SPR-based sensing devices and discusses the applicability of plasmonic sensors as point-of-care testing for virus particles and viral protein sensing.

Summary: In recent years, there has been a significant increase in the number of studies focusing on the synthesis and characterization of deep eutectic solvents (DESs). DESs, known for their stability, ease of synthesis, and ability to tailor properties, are considered one of the greenest solvent families used in various fields such as organic synthesis, catalysis, electrochemistry, and medicine. However, there is a lack of research on specific groups of DESs, particularly those comprising organic acids (OA-DESs), despite their potential in biomedical applications. This review aims to highlight the importance and applications of OA-DESs as antimicrobial agents and drug delivery enhancers, providing valuable insights for future developments in this field.

Summary: Diabetes poses major economic, social, and public health challenges worldwide and is a leading cause of foot ulcers and amputations. Lack of clinical imaging tools, insulin monitoring, and patients' adherence to treatment contribute to the diabetes epidemic. Advances in polymeric materials show potential for beta-cell imaging and non-invasive drug delivery in managing blood glucose and foot ulcers.
