Abstract

A method of depositing an antibacterial layer of material on a substrate, comprises the steps of generating a cloud of charged nanoparticles of an antibacterial material, and electrostatically accelerating the nanoparticles toward the substrate. Such a step of electrostatic acceleration allows a relatively fine degree of control to be exerted over the energy with which the nanoparticles impact the surface. This can thus be adjusted so as to give them sufficient energy to deform on impact and this create an adherent film, but not to deform so seriously that their nanoparticulate character is lost. Suitable materials include silver and copper. A nanoparticulate thin film coating is also described, comprising a plurality of at least partially merged nanoparticles. Each such nanoparticle can, in preferred films, define a local protruberance having a ratio of lateral versus perpendicular dimensions greater than 1.2:1.
