Modulation of Graphene Oxide Probiotic and Antibiotic Activity by Critical Coagulation Concentration

156a Sunday, February 12, 2017 has been conducted. Despite substantial efforts, results are controversial and a framework clarifying all effects reported in literature against bacteria still has to be defined. In our work, we demonstrate that by modulating the stability of GO in solution, the antibacterial or growth enhancement effect can been controlled both on S. aureus and E. coli bacteria. We expose these two species to concentrations of GO rangingfrom 3 to 200 ug/ml, in different incubation conditions (ultrapure water, PBS, NaCl, MgCl2 ...
