摘要：

Semi-interpenetrating carbohydrate polymer network [semi-IPN] hydrogels are composed with combination of carbohydrate polymers, chitosan and sodium alginate with 2-hydroxyethyl methacrylate. The semi-IPN carbohydrate hydrogels were successfully synthesized by using free radical polymerization technique. Silver nanopaticles were formed by reduction of silver nitrate in semi-IPN carbohydrate hydrogels with sodium borohydrate under room temperature. The formation of silver nanoparticles in hydrogels were well characterized by using UV-visible spectroscopy, thermo gravimetrical analysis, X-ray diffractrometry studies, scanning electron microscopy and transmission electron microscopy studies. Thermal and X-ray driffraction analysis confirmed the formation of silver nanoparticles in semi-IPN hydrogel. SEM images indicated clearly the formation of group of silver nanoparticles with size range of 10-20 nm. The sizes of silver nanoparticles were also supported by transmission electron microscopy results. The silver nanoparticles in semi-IPN hydrogel showed very good antibacterial activity on Escherichia coli, thus it reveals that the silver nanoparticles are acting as excellent antibiotics.
