Preparation, optimization and in vitro activity analysis of PVA/gelatin/sodium alginate-based (PGS) hydrogels loaded with Gardeniae Fructus Preparatus (JZZ) extract
{{output}}
In this study, polyvinyl alcohol (PVA) was introduced into the traditional gelatin (Gel)/sodium alginate (SA) system, and PVA/Gel/SA hydrogels (PGS) were prepared by freeze-thaw cycling and Cu2+ crosslinking. After screening, proper PVA/Gel ratios were found t... ...
