  • Publication number: 20100239678
    Abstract: The present invention is directed to attaching drugs 11 and other functional groups to surfaces of nano-sized diamond particles (NDs) 20 to enhance their efficacy. The method involves hydrating a plurality of nanodiamond (ND) particles 20 having a plurality of carbon chain surface molecules 23 on its surface. Cations 40 are embedded within the lattice structure 21 of the surface molecules 23 of the ND particles 20. The embedded cations 40 attract anions that cause crystalline growth. The anion form of drug molecules 11 are then grown on the crystal to cause the NDs 20 to be coated such that the active sites of said drug molecules 11 point away from the ND particle 20 exposing them for enhanced activity and enhanced drug efficacy. The efficacy of antimicrobial drugs 11, as well as other drugs 11 are enhanced by their attachment to the NDs 20.

  • Publication number: 20100129457
    Abstract: Drugs 11 and other functional groups are attached to surfaces of nano-sized diamonds (NDs) 20 to enhance the efficacy of drugs 11 such as analgesics, cholesterol-reducing drugs and other substances. Such coatings are formed by covalently linking NDs to the drug 11. NDs 20, due to its small size and spherical shape exhibits a large surface area which enhances contact with other substances and therefore the chemical reactions. The large surface area of NDs 20 covered with active drugs allows greater access to active sites of the drugs and allows a large amount of substance to come in contact with other chemical entities enhancing the reactions. NDs 20 are also a solution stabilizer allowing enhanced concentration and solubility of coated NDs 20, enhancing the ability of the active sites of drugs 11 to be dissolved and come in contact with corresponding sites 13,15 of other entities enhancing their efficacy.

  • Publication number: 20090226495
    Abstract: The present invention is directed to attaching drugs and other functional groups to surfaces of nano-sized diamonds (NDs) to enhance the efficacy of drugs and other substances. The method involved enhancing the efficacy of a drug having an active site by acquiring a plurality of nanodiamond (ND) particles having a plurality of carbon chain surface molecules on its surface. Intermediate amine entities are covalently attached to the surface molecules of the ND particles. These are then replaces with said drug molecules such that the active sites of said drug molecules point away from the ND particle exposing them for enhanced activity and enhanced drug efficacy. The efficacy of antimicrobial drugs are enhanced, however, this may be used with many different types of drugs.

  • Publication number: 20090187155
    Abstract: An absorbent article (1000) includes “beads” (111) that are modified to add functional groups (113). The functional groups (113) add antimicrobial, fire retardant, alcohol repellant and other properties. In addition, the beads (111) may be inert diamond, or conductive graphite. The substrate (101) of the article (1000) may be made with the beads (111) and functional groups (113) retaining the properties. The beads (111) and functional groups (113) may be incorporated into super absorbent materials (117) and attached to the substrate (101), with or without a binder (103). The resulting article (1000) therefore may have antimicrobial, fire retardant, alcohol repellant and antistatic properties making it specifically useful in medical applications. It may also be made as a multi-layered article (1000) having different amounts of super absorbent (“SA”) particles (1207, 1307, 1407) printed or embedded in patterns on each layer (1100, 1200, 1300, 1400), thereby channeling liquids.

  • Publication number: 20080060832
    Abstract: A novel method of designing and fabricating flexible and lightweight cable [100] having a central conductor [110], a dielectric layer [130], an outer conductor [150] and an insulation coating [170] using thin film technology is disclosed. The dielectric layer [130] is ‘grown’ on dielectric layer [130] using electrophoretic deposition to a specified thickness, based upon its intended use. It may include nano-diamonds. Ion beam assisted deposition is used to metalize the cable dielectric layer [130]. This may be ion beam assisted sputtering, ion beam assisted evaporative deposition or ion beam assisted cathodic arc deposition. In an alternative embodiment, the outer conductor may be etched to provide greater flexibility, or to add a piezoelectric layer. The central conductor [110] may be created from dielectric fibers [113] which are metalized as described above. The piezoelectric layer added to create ultrasonic transducer cables.

  • Patent number: 7068377
    Abstract: The present invention relates to microinterferometers and the application of such to profile surface geometries. A representative method for profiling a target surface of an object includes: illuminating the target surface with an incident light beam through a phase-sensitive, reflective diffraction grating, such that a first portion of the incident light beam is reflected and a second portion of the incident light beam is diffracted upon being transmitted through the diffraction grating; receiving interference patterns produced from the first portion of he incident light beam reflected from the diffraction grating interfering with the second portion of the incident light beam reflected from the target surface; measuring the intensity of the interference patterns to determine the distance to determine the distance between a reference point and the surface; varying the position of the object relative to the diffraction grating; and processing the measured distances to profile the surface of the object.
