Summary: Polyethylene terephthalate (PET) is widely used in medicine, engineering, and food due to its biocompatibility and mechanical resistance, but it lacks antimicrobial properties. In this study, PET film was functionalized with amino groups and a dicarboxylic acid, and then grafted with chitosan chains. The chitosan coating was loaded with silver nanoparticles, resulting in materials with good cell viability and potential bacteriostatic activity.

Summary: Composite nanofibers prepared by centrifugal spinning of poly(ethylene oxide) solutions containing silver nanoparticles exhibit strong antibacterial activity against Escherichia coli and Bacillus cereus. The nanofibers inhibit bacterial growth with over 98% efficiency and damage bacterial structure at the nanoscale due to the presence of silver nanoparticles. These results indicate that centrifugally spun poly(ethylene oxide)-Ag nanofibers are promising antibacterial agents for biomedical applications.

Summary: In this study, the stability and antibacterial activity of silver nanoparticles (AgNPs) coated with different stabilizers were investigated. The AgNPs showed differences in stability and size change depending on the coating agent used. The stabilizer may function as a growth controller of the nanoparticles, affecting their biological properties. The protective or stabilizing agents also played a role in the antibacterial capacity and stability of AgNPs over time.

Summary: In this study, silver nanoparticle-decorated 2D porphyrinic MOF nanosheets were prepared and demonstrated to have a high efficiency for antibacterial therapy. The nanosheets exhibited excellent antibacterial properties and achieved a sustained release of toxic Ag+ for a synergistic sterilization effect under laser irradiation. This effective strategy provides new insights for the applications of MOFs and contributes to the development of new antibacterial nanomaterials.

Summary: This study investigates the antibacterial properties of AgNPs with different pretreatment methods and develops a GO/AgNPs nanocomposite for polyacrylate emulsion. The results show that UV irradiation better maintains the antibacterial properties of AgNPs, while GO improves their dispersibility and prevents oxidation. The leather finished with the PA/GO/AgNPs composite emulsion demonstrates a high bacteriostatic rate.
