Summary: In this study, a simple and fast synthesis method for silver nanoclusters (AgNCs) was developed. The synthesized AgNCs exhibited fluorescence properties, which could be controlled by various factors. The fluorescence emission of the AgNCs depended on the excitation wavelength. Furthermore, the AgNCs were used as fluorescent probes for the detection of Cr3+ ions.

Summary: In this study, chitosan-coated magnetic silica nanoparticles were prepared and used for selective removal of silver ions from complex wastewater. These nanoparticles showed excellent selective adsorption performance in a wide pH range and maintained high adsorption capacity even in the presence of dyes. The adsorption process was chemisorption-controlled and exhibited a synergistic adsorption effect in the dye-metal binary system.

Summary: A new chitosan-trithiocyanuric composite (CS@TMT) was successfully synthesized and characterized in this study. The optimal synthesis conditions were determined using response surface analysis. CS@TMT exhibited higher adsorption capacity for Cr(VI) and Pb(II) compared to CS, and the adsorption process followed the pseudo-second-order kinetic model and Langmuir model. The reduction mechanism involved the -SH and -OH groups on CS@TMT, which reduced Cr(VI) to Cr(III) by 69.32%.

Summary: The physicochemical and biological properties of silver-casein complexes were investigated using various techniques. The study focused on the modification of casein using a novel method, which resulted in high colloidal stability and minimized metal secondary reduction risk. The sorption mechanism and the influence of protein ions on the silver binding process were studied. The results showed that the silver sorption had a complex character, and phosphoserine residues played a significant role in the interaction. The silver-casein complex exhibited effective inhibition of bacterial growth but showed toxicity towards fibroblast cells, possibly due to the release of Ag+ ions.

Summary: This study investigated the effect of amino-functionalized magnetic nanoparticles on the cytotoxicity of human cells before and after adsorption of Pb2+ ions. The results showed that the adsorbed Pb2+ ions had a toxic effect on the cells, and the cytotoxicity was dependent on the ion concentration. The adsorption of Pb2+ ions reduced their cytotoxicity, but oxidative stress remained.

Summary: Bacterial motility can be a significant predictor of AgNP resistance, guiding the development of nanoenabled antimicrobials. The study of bacterial resistance to AgNPs is still in its early stages, with limited understanding of the underlying mechanisms. The resistance to subinhibitory concentrations of AgNPs in Escherichia coli K-12 MG1655 strain was found to be associated with a cusS mutation, potentially enhancing silver ion efflux and suggesting a role for flagellum-based motility in the resistance mechanism.

Summary: Two novel porous polymer matrix nanocomposites were synthesized and used as adsorbents for heavy metal uptake, showing maximum adsorption capacities of 105.3 and 109.9 mg g(-1) for methacrylate-modified FDU-12/poly(methyl methacrylate) and amine-modified FDU-12/Nylon 6,6, respectively. Langmuir and pseudo-second-order models were found to be the best fit for predicting isotherms and kinetics of adsorption.
