Bullets That Snag DNA

From Popular Science (Jan. 2013):

A team of nanomaterials scientists led by Paul Sermon, of Brunel University in England, has developed a bullet that captures the DNA of anyone who touches it—and leaves a tracer on the person, too.

Scientists dipped a bullet in a formaldehyde-urea resin, creating a microscopic scratchy surface that snags skin cells. When fired in lab tests, the bullet retained 53 percent more analyzable DNA than an untreated one. [read more]

Interesting idea but like someone said in a comment what will this do to the price of bullets? And since different guns use different bullets will every type of bullet have this ability? Probably. And if someone uses gloves to load a gun then there won’t be any DNA on the bullets especially if a careful criminal finds out about the technology.
