Spire Corp. has received a two-year, $750,000 SBIR Phase II grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases to develop nanotechnology coatings.

Under the grant, Spire will develop hard, extremely adherent nanocrystalline coatings for orthopedic implants. The coatings contain metallic bonding and have a chemical composition very similar to the substrate. Feasibility of the technology was demonstrated during a Phase I grant. Phase II will optimize coating properties and demonstrate performance in a joint simulator, ultimately leading to commercial application of the coating.

Mark Little, CEO of Spire, stated, "Coating orthopedic device surfaces as a means of reducing wear and extending device performance has been considered a promising approach for many years. However, the inability to obtain a sufficiently adherent coating by conventional means has severely limited its application. Our coatings have the potential for overcoming the adhesion problem and significantly improving orthopedic device function and lifetime."
