Abstract
The present study deals with the green synthesis of silver nanoparticles (Ag NPs) using a chemically modified polysaccharide as a reducing and capping agent. Dextran succinate (Dex-Suc) was synthesized by succinylation of the dextran with succinic anhydride at 80 °C for 24 h under stirring and N2. The Dex-Suc was used as a reducing and capping agent for the synthesis of Ag NPs in the presence of sunlight with high UV index. The Ag NPs were characterized using UV-Vis spectroscopy, SEM, and EDS techniques. The SEM data revealed the preparation of spherical Ag NPs having 50 nm size. The Ag NPs showed antimicrobial properties against different bacterial and fungal strains.
