Abstract
The invention is directed to efficient methods for depositing highly adherent anti-microbial materials onto a wide range of surfaces. A controlled cathodic arc process is described, which results in enhanced adhesion of silver oxide to polymers and other surfaces, such as surfaces of medical devices. Deposition of anti-microbial materials directly onto the substrates is possible in a cost-effective manner that maintains high anti-microbial activity over several weeks when the coated devices are employed in vivo.
