Researchers from Hunan University Report Recent Findings in Nanocomposites (Inactivation performance and mechanism of Escherichia coli in aqueous system exposed to iron oxide loaded graphene nanocomposites)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Nanocomposites. According to news originating from Changsha, People's Republic of China, by NewsRx correspondents, research stated, "The challenge to achieve efficient disinfection and microbial control without harmful disinfection byproducts calls for developing new technologies. Magnetic-graphene oxide (M-GO) with magnetic iron oxide nanoparticles well dispersed on graphene oxide (GO) nanosheets exerted excellent antibacterial activity against Escherichia coil."

Our news journalists obtained a quote from the research from Hunan University, "The antibacterial performance of M-GO was dependent on the concentration and the component mass ratio of M/GO. The synergetic antibacterial effect of M-GO was observed with M/GO mass ratio of 9.09. TEM images illustrated the interaction between E. coil cells and M-GO nanocomposites. M-GO nanomaterials were possible to deposit on or penetrate into cells leading to leakage of intercellular contents and loss of cell integrity. The inactivation mechanism of E. coil by M-GO was supposed to result from both the membrane stress and oxidation stress during the incubation period."

According to the news editors, the research concluded: "M-GO with excellent antibacterial efficiency against E. coil and separation-convenient property from water could be potent bactericidal nanomaterials for water disinfection."
