Summary: An antibacterial coating containing GO/ZnO/Cu2O was successfully sprayed on glass fibers using hydrothermal synthesis and air spraying techniques. The coating exhibited excellent antibacterial properties and stability, with a 100% antibacterial rate against E. coli and S. aureus. The photochemical activity of the coating was significantly improved, which confirmed the photocatalytic/oxidative stress mechanism.

Summary: This study developed chitosan/gelatin nanofiber membranes with sustained release capacity to prevent infection by delivering cinnamon extract (CE) in the implanted site. The incorporation of CE enhanced the properties of the nanofibers, including degradation behavior, antibacterial activity, and biocompatibility. The extract release profile showed a burst release in the first 6 hours, followed by a controlled release in the next 138 hours.

Summary: The overuse or abuse of antibacterial drugs has resulted in serious health issues. Among various antimicrobial materials, especially ZnO, inorganic antimicrobial materials have gained wide attention. However, agglomeration is an important factor that affects the function of nanoparticles and compromises the antibacterial properties of ZnO. This study utilizes talc as a substrate to control the size and dispersion of ZnO, creating composite minerals with excellent antibacterial properties against Escherichia coli and Staphylococcus aureus.

Summary: The swelling behavior of whey-based hydrogel samples with increasing concentrations of graphene oxide (GO) was investigated using nuclear magnetic resonance (NMR) and mathematical models. GO was found to improve the mechanical and swelling properties of the hydrogels at low concentrations. The swelling process followed first-order kinetics for the initial <60% swelling and second-order diffusion for the whole time interval. Higher concentrations of GO led to higher cross-linking and reduced swelling capacity. Only hydrogel samples with higher GO concentrations showed antibacterial activity.

Summary: Smart and controllable antibacterial fabrics have great potential in textile, medical, and healthcare fields. In this study, a composite antimicrobial fiber with thermally responsive properties was created by synthesizing nano zinc oxide (ZnO) and combining it with quaternary ammonium chitosan (QAC). The addition of a copper sulphide (CuS) layer further enhanced the antibacterial properties of the materials. These smart responsive composite fibers show promise in medical dressings, special textiles, and healthcare materials.
