Preparation of carboxymethyl guar gum/silver nanocomposites film and its optical and antimicrobial properties

Abstract: Carboxymethyl guar gum/silver nanocomposites (CMGG/Ag NC) film was prepared by solution castings method. The aim of this paper was to study optical and antimicrobial activity of the film. The formation of nanocomposites film was confirmed by using SEM, TEM and XRD analysis. Optical properties of the film were tested by UV-Vis and Photoluminescence spectroscopy (PL) respectively. Antimicrobial activity of the CMGG/Ag NC film was studied against gram positive (Bacillus subtilis) and gram negative (Escherichia coli) bacteria by Kirby-Bauer method. It was found that a little amount of CMGG/Ag NC film was sufficient to inhibit pathogens. The result concludes that such prepared silver nanocomposites film may be effective in medical and clinical applications.
