A bifunctionalized NiCoO-Au composite: Intrinsic peroxidase and oxidase catalytic activities for killing bacteria and disinfecting wound.

A NiCoO-Au composite was fabricated following the calcination-reduction method and testified to exhibit the intrinsic high peroxidase- and oxidase-like activities. The composite could activate a low level of HO (100 μM) to kill E. coli and S.
