Antibacterial Characteristic of Spherical Carbon Containing ZnO

Abstract

Spherical and hard carbon particles containing ZnO at highly dispersed state were prepared by carbonizing an ion-exchange resin exchanged by Zn²⁺. They were subjected to the evaluation of antibacterial activity against the growth of S. aureus. It was found that the antibacterial activity increased with increasing amount of the carbon particles in an incubation cell.
