Abstract: The invention is directed to an ion plasma deposition (IPD) method adapted to coat polymer surfaces with highly adherent antimicrobial films. A controlled ion plasma deposition (IPD) process is used to coat a metal or polymer with a selected metal/metal oxide. Exposing the coated surface to ultraviolet light significantly improves the antimicrobial properties of the deposited coatings.

Abstract: A molecular plasma deposition (MPD) method in combination with an atomic layer deposition (ALD) procedure is used to produce amorphous, nonconformal thin metal film coatings on a variety of substrates. The films are porous, mesh-like lattices with imperfections such as pinholes and pores, which are useful as scaffolds for cell attachment, controlled release of bioactive agents and protective coatings.

Abstract: Vapor plasma deposition of titanium (Ti) metal onto a substrate forms a structured surface that exhibits enhanced cell attachment properties. Initially deposited round nanoparticulate surface structures develop tentacles with a spine or thorn-like appearance upon continued deposition under special conditions. The density and size of the formed spinulose particles can be controlled by timing the deposition intervals. A significant increase in osteoblast, fibroblast and endothelial cell attachment is observed on Ti spinulose surfaces compared to attachment on nanoparticulate surfaces lacking spinulous nanostructure.

Abstract: The invention is directed to efficient methods for depositing highly adherent anti-microbial materials onto a wide range of surfaces. A controlled cathodic arc process is described, which results in enhanced adhesion of silver oxide to polymers and other surfaces, such as surfaces of medical devices. Deposition of anti-microbial materials directly onto the substrates is possible in a cost-effective manner that maintains high anti-microbial activity over several weeks when the coated devices are employed in vivo.

Abstract: An apparatus and method for initiation and control of a sustained metal plasma and nano plasma (macroparticulate) deposition methods for preparing modified metal coatings are provided. The plasma deposition process can be tightly controlled by virtue of a device that incorporates a plasma arc initiator component and an internal power supply that is capable of controlling dwell time on the target and the size range of particles ejected in the plasma arc.
