Abstract: The present disclosure provides biocidal metal particles, and methods for production thereof. The method of producing the biocidal materials includes thermally spraying, into a collection system, a feed material having a metal mixture having from about 2% to about 96 wt. % Cu, about 2 to about 96 wt. % Zn, and about 1 to about 40 wt. % Ni, under conditions to give particles with a size in a range from about 1 to about 50 microns. The metal particles are collected and are characterized in that they have an amorphous solid structure and exhibit enhanced biocidal properties.

Abstract: A method of producing substrate having an antimicrobial surface by thermally spraying the surface with metals such as copper and alloys of copper, silver and alloys of silver, zinc and alloys of zinc, tin and alloys of tin and combination thereof and thereafter abrading the sprayed surface to give the surface antimicrobial properties.

Abstract: A substrate having an antimicrobial surface. The texture of the surface which has exposed metal e.g., copper or copper alloy contributes to the antimicrobial properties. Cavities or depressions in the surface can be coated or partially coated with an organic polymer, and the polymer can contain antimicrobial agents. Methods of preparing a coated surface, and uses are described.

Abstract: The present invention provides a method of depositing one or more layers of metal coatings onto an organic substrate. The method includes providing a source of a jet of molten metal particles having an average temperature within a predetermined range, an average velocity within a predetermined range. The jet of molten droplets is then directed at a surface of an organic substrate thereby depositing a metal coating on said organic substrate surface. The source of droplets is spaced from the organic substrate a pre-determined distance, and the average velocity and the average temperature are selected for a given metal such that the temperature of the molten metal particles is very close to the melting point of the metal as the molten droplets coat the surface of the organic substrate to minimize damage to the organic substrate.
