Abstract:
A method to link a light emitting reporter to biomolecules with nucleotide oligomers is described. The light reporter particles are silylated and functionalized to produce a coated light reporter particle, prior to covalently linking the biomolecules to the light reporter particle. The light reporter particle generated by the methods of the invention can be excited by a light excitation source such as UV or IR light, and when the biomolecule is DNA, the attached DNA molecule(s) are detectable by amplification techniques such as PCR.
Abstract:
This invention pertains to methods for authenticating an article comprising tagging the article with light emitting optical reporter particles, and more specifically tagging the articles with up-converting phosphor particles (UCP), linked to nucleic acids of detectable sequence.
Abstract:
Methods for distinguishing between cotton cultivars of a specific species by analyzing a sample of mature cotton fibers from raw cotton materials or from textile goods are disclosed. DNA is extracted from the mature cotton fiber sample and subjected to PCR techniques which enable the identification of the cultivar of a particular cotton species utilized in the textile or cotton material of interest.

Abstract:
A method for authenticating and verifying a pharmaceutical item to be genuine is described. The method for authenticating a tablet comprises applying a particular nucleic acid material associated with a particular sequence of nucleic acid bases to a tablet or capsule. The method also comprises collecting a sample of the tablet and verifying the tablet is genuine by detecting the particular nucleic acid material.
