HIGHLY MICROBIAL RESISTANT GRAPHEME OXIDE NANOPARTICLES: SYNTHESIS, CHARACTERIZATION AND ITS ANTIBACTERIAL ACTIVITY

ABSTRACT: The present work deigned to prepare graphene oxide nanoparticles and their antimicrobial activity has been evaluated. Graphene oxide is a singal layer of carbon arranged in a hexagonal pattern the basal planes and the edges of graphene oxide nanoparticles contain functional exogenous groups such as hydroxyl, carbonyl and epoxy group, which not only expand the interlayer distance but also make the atomic thick layer hydrophilic. Most important application in area related to transparent conductive film, composite materials, solar energy and biomedical application. Present work based on Hummer’s method which is most common used for preparing graphene oxide. The result graphene oxide was characterized by UV-Vis Spectra and SEM. The graphene oxide nanoparticles absorption peak was occurred at 289nm in UV-Vis spectra. SEM analysis showed the average particles size of 50-60nm corresponding to Hummer’s method respectively. Its antbacterial activity tested against gram negative and gram positive bacterial (Bacillus subtilis, Enterobacter aerogenes, and Staphylococcus epidermis) strain. Graphene oxide nanoparticles of Hummer’s method showed the best inhibitory effect against Staphylococcus epidermis in comparison to other bacterial strain
