  • Patent number: 8808756
    Abstract: The present application is directed to a coating composition comprising a ceramic binder and inorganic copper compound particles. Generally, the inorganic copper compound particles have a median particle size of less than 5 micrometers. In some embodiments, the particles have a median particle size of greater than 1 micrometer. The inorganic copper compound particles may be non-photocatalytic. The coating may also be placed on a structural layer.

  • Patent number: 6881203
    Abstract: Microneedle arrays, methods of manufacturing microneedles and methods of using microneedle arrays. The microneedles in the microneedle arrays may be in the form of tapered structures that include at least one channel formed in the outside surface of each microneedle. The microneedles may have bases that are elongated in one direction. The channels in microneedles with elongated bases may extend from one of the ends of the elongated bases towards the tips of the microneedles. The channels formed along the sides of the microneedles may optionally be terminated short of the tips of the microneedles. The microneedle arrays may also include conduit structures formed on the surface of the substrate on which the microneedle array is located. The channels in the microneedles may be in fluid communication with the conduit structures. One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue.
