An antimicrobial coating composition comprising a nanoparticle composite having a core and at least one shell, wherein the core comprises a silver nanoparticle having an antimicrobial action. The at least one shell is formed by a doped semiconductor providing a photocatalytic action and increasing the stability of silver nanoparticle core by controlling the releasing of Ag ions. The nanoparticle composite comprises a nanoparticle of a noble metal providing surface plasmon under the presence of electromagnetic radiation. |
