Development of a Biopolymer-Based SA/PVA/Saffron Hydrogel Incorporating ZnO-Chitosan Nanocomposite

A biopolymer-based hydrogel composed of polyvinyl alcohol (PVA) and sodium alginate (SA) was developed, incorporating saffron extract and green-synthesized ZnO nanoparticles coated with chitosan (ZnO NPs-Chsn). FE-SEM and EDX analyses confirmed a porous network structure and successful incorporation of nanoparticles. The presence of ZnO NPs-Chsn significantly enhanced the hydrogel's swelling and porosity, with water uptake increasing from ۲۲۰.۹ _x۰۰۰۰_b۱ ۱.۸۹% to ۵۸۹.۴ _x۰۰۰۰_b۱ ۱.۷۷% and porosity from ۳۱.۱ _x۰۰۰۰_b۱ ۱.۰۳% to ۹۰.۷ _x۰۰۰۰_b۱ ۱.۸۳%. These findings indicate that the hydrogel possesses favorable structural and physicochemical properties, suggesting its potential suitability for biomedical applications.
