Scientists develop new DNA analysis tool that can help nab criminals


MELBOURNE: Scientists have developed a new test that can reveal the amount of DNA people shed, a tool that could be used by forensic experts to nab criminals using genetic clues left at crime scenes.

A single tap of a finger on items like door handles, glass or even shaking hands can help identify and link potential suspects to a crime. Modern DNA forensic science is capable of analysing microscopic genetic traces inadvertently left at crime scenes.

However, accurate identification depends on the quality of DNA sourced at the scene, according to a researcher at the Flinders University in Australia.
