  • Patent number: 5770255
    Abstract: Anti-microbial coatings and method of forming same on medical devices. The coatings are formed by depositing a biocompatible metal by physical vapor deposition techniques to produce atomic disorder in the coating such that a sustained release of metal ions sufficient to produce an anti-microbial effect is achieved. Preferred deposition conditions to achieve atomic disorder include a lower than normal substrate temperature, and one or more of a higher than normal working gas pressure and a lower than normal angle of incidence of coating flux.

  • Patent number: 5124172
    Abstract: A thin film diagnostic device capable of detecting the presence of a specific organic material in a sample solution. The device comprises a layer of an anodizable color-generating metal (e.g. tantalum), a porous anodic film containing aluminum oxide overlying the color generating metal, and a reagent capable of binding with the specific organic material forming a coating on the anodic film. The porous anodic film and the coating have a combined thickness such that a color change is produced when the specific organic material binds to the reagent. The device can be used to test the biological or synthetic products in samples taken from patients or other sources.

  • Patent number: 5039559
    Abstract: Magnetically attractable particles comprise a core of magnetic material encapsulated in a metal oxide coating. They may be made by emulsifying an aqueous solution or dispersion of the magnetic material or precursor, and an aqueous solution or sol of a coating inorganic oxide or precursor, in an inert water-immiscible liquid. The aqueous droplets are gelled, e,g. by ammonia or an amine., recoverd, and heated at 250.degree.-2000.degree. C. The resulting particles are generally smooth spheres below 100 microns in diameter and often of sub-micron size.
