Preparing and Antimicrobial Activity of Hydrogel with Biosynthesized Silver Nanoparticles Using Carex Meyeriana Kunth

In this study, a simple and environmentally stable method was developed to synthesize silver Nanoparticles (AgNPs). In addition, carex meyeriana kunth was used as a reducing and stabilizing agent with good bacterial inhibitory effects against Escherichia coli (E. coli) and Bacillus subtilis at very low doses. AgNPs were added to the Polyvinyl Alcohol (PVA) solution as an antibacterial agent and AgNPs-loaded PVA hydrogel (gel) was formed using the freeze-thaw method. The hydrogel containing AgNPs had a powerful antibacterial effect and the PVA/Ag hydrogel was tested as a trauma dressing, which is a promising composite material for development. © 2023 Qihui Shen, Henan Zhu, Hongli Zhou, Tienan Jiang and Yan Liu.
