(a) Cytotoxicity of GO coating on HA-ATi to E. coli and S. aureus exposed to various concentrations of GO coating on HA-ATi samples, for 24 h. The value was calculated using one-way ANOVA; ; . Cyclic voltammograms of detected (b) S. aureus and (c) E. coli ROS. The bacteria were incubated on GO-HA-ATi and CV was measured in PBS electrolyte at room temperature after 24 h.
