Abstract

ABSTRACT: We developed an antiviral ceramic coating for immediate and long-term enveloped virus inactivation. The coating consisted of a porous ceramic coating fabricated by aerosol deposition and filled with chlorhexidine (CHX). The coating immediately inactivated enveloped viruses by releasing CHX. Furthermore, after the coating was repeatedly washed to simulate practical use, it still showed antiviral activity because CHX leakage was suppressed by the nanopores in the coating. We expect our antiviral coating to exhibit antiviral activity under conditions similar to practical use.
