    摘要： The invention provides a method of marking an item with naturally-derived or synthetic non-natural polymeric marker molecules, such as a DNA or Peptide marker in conjunction with optional visible or rapid scan reporters for authenticating or tracking, in which the method includes providing an item for marking, and applying a medium including a DNA marker to the item. The invention further provides methods for stably binding and immobilizing activated deoxyribonucleic acid onto objects and substrates. The method includes exposing the deoxyribonucleic acid to alkaline conditions, and contacting the deoxyribonucleic acid to the object or substrate. Also provided are methods for increasing the recoverability of taggants from an object. The methods include the steps of incorporating a taggant into a solution; mixing the solution including the taggant with a perturbant to form a first perturbant taggant solution; mixing the first perturbant taggant solution with a polymer to form a second perturbant taggant polymer solution; and applying the second perturbant taggant polymer solution to at least a portion of the object to form a taggant-coated object. The invention also provides a method of marking an item with a DNA marker for authenticating or tracking, in which the method includes providing a medium including a DNA marker, and molding the medium including the DNA marker to provide all or part of the item. The DNA marker encodes information unique to the item and/or the model of the item as desired.

    摘要： Encrypted markers that are not readily detectable can be revealed by treatment with a specific reagent used as a developer to reveal a readily detectable physical property of the marker, such as a characteristic fluorescence emission after excitation with a particular excitation wavelength, or to reveal a visible color. The encrypted marker can be developed in situ, or a sample can be removed by brushing, scraping, swabbing or scratching the marked object or item and developing the encrypted marker or a sample thereof with the appropriate developer to reveal an overt marker or optical signal. The marker can be revealed by exposure of the encrypted marker or a sample thereof to the developer in any suitable form, such as a solution, a slurry, a swab, a solid (such as in granular form), or a gas or a vapor that includes a developer.

    摘要： This invention provides compositions that have a light emitting reporter linked to biomolecules, preferably, nucleotide oligomers. 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 particles 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.
