Abstract
Green synthesis of silver nanoparticles (AgNPs) using rice husk (RH) as low-cost agricultural waste material has been gaining importance in recent years. Meanwhile, poly (vinyl alcohol) (PVA) is reported to involve in the green production of AgNPs as low-cost, water-soluble, biocompatible and biodegradable stabilizing polymer. The present study is focussed on the green synthesis of poly (vinyl alcohol) (PVA) - silver nanoparticles (PVA-AgNPs) hybrid using rice husk extract as a reducing agent. The results recorded from UV–vis spectrum and transmission electron microscopy (TEM) support the characterization of AgNPs produced. Synthesised PVA-AgNPs hybrid revealed effective antibacterial activity against Escherichia coli and Bacillus sp.
