Abstract
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.
