Assessing Graphene Oxide (GO) and CuO Nanocomposites for Effective Antibacterial Properties Using Laser Interferometry

Nanoparticles of CuO have been synthesized by the sol-gel technique and their structural, optical and chemical properties were studied to assess their antibacterial properties. These nanoparticles were found to be excellent anti-biotic againstE.coli and cocci gram-positive. Graphene oxide (GO) nanopar-ticles were also synthesized by hummers modified method and their optical, chemical and structural properties were confirmed. A composite of CuO and GO has also been prepared by sonication method. Using laser interferometry its ultraviolet (UV)-visible (VIS) spectrum has been observed to be consistent with its reference UV-VIS spectrum, which verified the formation of nano -composite. The composites were prepared in suspension form, and were used for antibacterial activity, appeared to be a great antibacterial substance against two different types (E.coli and pseudo) of gram-positive bacteria.
