But the benefits of the nanotechnology don’t stop there. Most evidence is usually destroyed after a gun is fired, because of the heat generated. The coating has been designed to avoid such heat damage and can even be varied subtly for every cartridge batch, making it easier for officials to tie guns back to the offenders. The breakthrough technology is cost-effective and could potentially be put to use within a year. Researchers may also consider applying the system to other weapons like knifes. Via PhysOrg
