“…Additionally, an antibacterial coating made of poly( l ‐lysine)/hyaluronic acid multilayer films and liposomes loaded with Ag + was also explored 34. The strong antibacterial effect was attributed to the diffusion of Ag + from the AgNO 3 coating, which resulted in Ag + aggregation around the membranes of bacteria.…”

Antibacterial materials are recognized as important biomaterials due to their effective inhibition of bacterial infections. Hydrogels are 3D polymer networks crosslinked by either physical interactions or covalent bonds. Currently, hydrogels with an antibacterial function are a main focus in biomedical research. Many advanced antibacterial hydrogels are developed, each possessing unique qualities, namely high water swellability, high oxygen permeability, improved biocompatibility, ease of loading and releasing drugs, and structural diversity. Here, an overview of the structures, performances, mechanisms of action, loading and release behaviors, and applications of various antibacterial hydrogel formulations is provided. Furthermore, the prospects in biomedical research and clinical applications are predicted.

“…356 Liposomes were also used to trap silver within a polymer coating. In fact, Malcher and co-workers 357 could make an antimicrobial composite containing liposomes filled with silver nitrate using a sonication technique. They first filled the liposomes with silver nitrate solution, and then, with the help of poly(L-lysine) (PLL), they forced these liposomes to aggregate.…”

“…Gold nanoparticles (AuNP), silver nanoparticles and liposomes have been previously deposited onto such films. [32][33][34][35][36] It was observed, that nanoparticles are located at the surface of films. [34] Here we report that the film stiffness depends on the concentration of nanoparticles.…”
