Preparation of GO-ZnO Nanocomposite and its Antibacterial Activity

Abstract

The progression of nanomaterials demonstrated prevailing apparatuses for nanotechnological sales in various kinds of application like electronics, drug deliver carriers, biosensors and nanomedicine. By and large, nanoparticles appear to be a double-edged sword as they have both valuable and unsafe impacts, depending upon the circumstance of applications. Graphene and its family derivatives like graphene oxide (GO) is the allotrope of carbon and reduced graphene oxide (RGO) also allotrope form of carbon attract in the entire world because of its outstanding physiochemical properties, for example, huge surface area to volume proportion, magnificent charge transportation, great quality and low electrical noise. Graphene based nanomaterial and its composites for example GO-ZnO in a biological point of view require an detailed origination with outstanding antibacterial properties with decline toxicity quality and morphological evaluations of these materials is as yet appealing test for future interest. Here, in this experimental work, we have synthesized and characterized GO-ZnO by X-ray diffraction (XRD), Uv-Vis spectroscopy, Field emission scanning electron microscopy FESEM, for morphological and essential study. Toxicity of GO-ZnO nanocomposite was surveyed by means of methyl-thiazole-tetrazolium (MTT) measure, and morphological changes realize GO-ZnO in Escherichia coli (E.coli) investigated by confocal checking electron microscopy with magnification of ×40. The toxicity of GO-ZnO nanoparticle was assessed by estimating the degree of misfortune in cell viability (%) in dose dependent which caused the cell destruction in apoptotic/necrotic way. The reason of bacterial death due oxidative pressure trigger by reactive oxygen species (ROS) expressed potential role of GO-ZnO for enhancement of antimicrobial activity of E coli as an effective antibacterial specialist.
