    摘要： A method of marking an inventory item includes providing an activatable smoke generator and a reservoir for holding a smoke fluid and adapted to provide a flow of smoke fluid to the generator. The reservoir contains a smoke fluid including a carrier nucleic acid having a uniquely identifiable sequence, and upon activation of the smoke generator, marker smoke is generated and targeted to flow over the inventory item. The method further includes activating the smoke generator to produce the marker smoke including the carrier nucleic acid so as to cause the marker smoke to flow over the inventory item and thereby to detectably mark the inventory item with carrier nucleic acid. The invention provides methods for stably binding and immobilizing 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. The alkaline conditions are produced by mixing the deoxyribonucleic acid with an alkaline solution having a pH of about 9.0 or higher, and contacting the deoxyribonucleic acid to the substrate. The immobilized DNA can be used as a taggant and can be used in combination with other detectable taggants, such as optical reporters.

    摘要： A multi-mode reader instrument capable of detecting and determining digital data from a signal from one or more markers, indicia or taggants on an object, the markers, indicia or taggants such as a bar code, a QR code, an RFID, an optical compound, a fluorescent compound, a phosphorescent compound, a DNA taggant, an upconverting phosphor (UCP), a chemical dye, a digitized image, a radioactive compound, an olfactory compound or a thermal attribute of the object is provided. Also, provided is a method and a system for identifying an object, the system includes: a multi-mode reader instrument for detecting data from a signal from one or more markers, indicia or taggants on an object and assignment of digital code for the marker and a database for securing and retrieving information relevant to the item.

    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： A method of marking fibers, wherein the method includes providing a plurality of fibers; depositing a marker onto at least a portion of the fibers, the depositing being performed with a delivery mechanism comprising one or more outlets; and thereby marking the fibers. Also provided is a device for marking fibers, including a transport system adapted to transport fibers in a direction of a marker delivery apparatus positioned along the transport system; the delivery apparatus includes one or more outlets, adapted to deposit a solution of the marker through the outlets onto at least a portion of the fibers; and thereby marking the fibers. Authentication of a fibrous material using the marking method of the invention followed obtaining a sample of the marked fibers and assaying the sample for the presence of the nucleic acid marker; and thereby determining whether the fibrous material is authentic or counterfeit.
