title: Cytotoxicity and Antibacterial Characteristics of Graphene-Oxide Nanosheets Toward Human Pathogens.
abstract: Nanomaterials show great opportunities in the development of electronics, biosensors, chemical and industrial applications. In this article, we are reporting the cytotoxicity and antibacterial characteristics of graphene-oxide (GO) nanosheets toward selected human pathogens. GO is prepared by using modified Hummers method. The prepared GO is characterized using X-ray diffraction, Raman analysis and transmission electron microscopy. Our studies confirmed the antimicrobial activity of GO against various human pathogens. The cytotoxicity effects of GO nanosheets are investigated using MTT assay which confirms that GO nanosheets are non-toxic and eco-friendly. These results ensure that GO nanosheets can be a potential antibacterial agent in the biological, health related industry development and applications.
