Antimicrobial materials and coatings

摘要

Durable antimicrobial coatings which may be deposited on a substrate. Such coatings may include a plurality of particles which are fused to the substrate and/or other particles. The particles may be provided using a single-sided electrode arrangement, which is configured to produce an electrical arc or discharge at one end of an electrode and to emit the particles from the electrode, where the arc or discharge can be produced without the end of the electrode being in proximity to a grounded object. The particles may be provided as one or more layers of nanoscale particles having an average size of less than about 1000 nm. Such coatings may have a thickness that is less than about 1000 nm. Thicker coatings may also be provided. The coatings may preferably include silver, tungsten, noble metals, nonstoichiometric compounds including ceramics, other metals including rare earth metals and compounds, and compositions thereof.

1. A structure comprising: a substrate, and a porous coating applied to a surface of the substrate, wherein the coating comprises a plurality of partially sintered particles and wherein an average size of the particles is less than about 800 nm, wherein each of the particles at least partially adheres to at least one of the substrate or another one of the particles, wherein the particles that at least partially adhere to the substrate are fused to the substrate, wherein at least one portion of the substrate is covered by the coating, and wherein the coating exhibits antimicrobial properties resistant to chemical attack.
