Negative charges on sharp-edged single-sheet GO and rGO were shown to bind and to suppress the infection of pseudorabies, PEDV, EV71, and H9N2 viruses.181,182 This mechanism suggests that potentially similar antiviral effects could be offered by other negatively charged, sharp-edged 2D nanomaterials such as Ti3C2Tx MXene, which has shown promising bacterial inactivation effects against both Gram-positive and Gram-negative species due to similar hypothesized mechanisms.118,183
