SYNTHESIS AND CHARACTERISATION OF HERB FABRICATEDCHITOSAN-SILVEROXIDE NANOCOMPOSITES

Abstract

This research work explains the synthesis of chitosan-silver oxide nanocomposite and
medicinal herb were loaded by swelling method. The synthesised nanocomposites were
characterised by UV-VIS, FTIR spectroscopy. The scanning electron microscope (SEM)
results showed that particles were spherical in the size range of 50-100 nm. The antibacterial
activity of the nanocomposites was assessed by agar well diffusion method. Our studies
proved that the chitosan as biomaterial based nanocomposites containing silver oxide has an
excellent antibacterial activity.
