Chimeric DNA identifier

摘要

Devices and methods for delivering a chimeric deoxyribonucleic acid (DNA) marking agent to a target and identifying the target from the chimeric DNA marking agent are provided. A delivery device may be a projectile, a spray canister or a wet/dry article. The chimeric DNA marking agent includes unique DNA fragments and may also include a fill material such as a liquid, a gas or a powder. The chimeric DNA marking agent may be combined with any combination of general marking agent, an inhibiting agent, an immobilizing agent, a weighting agent and a protective agent. The DNA marking agent may be analyzed using any of a hybridization method utilizing a labeled probe, a gel electrophoresis method, determining the base sequence to confirm a predefined DNA sequence, amplifying at least one of the unique DNA fragments and using a polymerase chain reaction (PCR) method.

主权项

1. A device for delivering a chimeric deoxyribonucleic acid (DNA) marking agent to an exterior surface of a target, comprising:
a housing comprising a projectile, the projectile having a solid outer shell and being capable of being launched towards a target, the projectile further comprising a semi-hemispherical body portion having a first cavity, a generally cylindrical body portion having a second cavity, and a divider separating the first cavity from the second cavity; a chimeric DNA marking agent sealed within one of the first cavity and the second cavity, wherein the chimeric DNA marking agent comprises two or more unique DNA fragments; wherein at least one of the first cavity and the second cavity is at partially filled with one of a general marking agent, an inhibiting agent, an immobilizing agent, and a weighting agent; and the projectile capable of fracturing upon contact with the exterior surface of the target to release the chimeric DNA marking agent onto the exterior surface of the target.
