  • Patent number: 8034569
    Abstract: This invention relates to methods for molecular detection, particularly to methods utilizing target-specific molecular probes. In exemplary embodiments, target-specific molecular probes include single-stranded deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) aptamers. In general, the molecular probe may bind with relatively high specificity to a given target. In one aspect, a method for molecular detection comprises a molecular probe paired to a reporter molecule wherein the molecular probe impairs the amplification of the reporter molecule in the absence of the target molecule.

  • Patent number: 7201578
    Abstract: A method for whitening teeth which utilizes laser light to activate bleaching agents applied to the teeth. The mouth is first prepared so that the soft tissues of the gums are protected and only the teeth are exposed. The teeth are cleaned to remove any materials which will reduce or nullify the effects of the bleaching agents. A first bleaching composition comprising a peroxide compound is prepared and applied to the teeth. The teeth are exposed to laser light from an argon laser which light activates the peroxide to accelerate the bleaching process without heat. If further whitening is desired, a second bleaching composition comprising a peroxide compound is prepared and applied to the teeth. The teeth are briefly exposed to laser light from a carbon dioxide laser which heat activates the peroxide to accelerate the bleaching process.
