Pollen Based Nanotags on Bullets Could Help Pinpoint Criminals

Nanotechnology may soon be used to track a bullet and everyone who handled it. A group of British researchers are developing a solution that merges natural pollen with nanoparticles and it is proving to be durable enough to survive the heat of a bullet firing.

The particles are very difficult to clean off, and will keep skin particles adhered to the bullet as well as attaching themselves to anything that handles the bullet, including skin and gloves.  The nanotags are only 30 microns in diameter and are invisible to the naked human eye.  This leaves a forensic trail that can tie a bullet back to the person who handled the bullet.  The coating gives a double chance of pinpointing the shooter by either forensic evidence left by the bullet or DNA material captured on the bullet, making it a very effective tool.

The cost of the coating is said to be very economical, and the team believes that they can have it ready for production within a year.
