<p>An anti-microbial composition includes particles having an outer surface onto which an anti-microbial agent has been adsorbed. The particles can be used, for example, for coating the bristles of toothbrushes. The particles preferably are polymeric, e.g. polymeric microspheres such as polystyrene microspheres. The anti-microbial agent may be, e.g., chlorhexidine.</p> |
