A biochemical eyewitness

Blood found at a crime scene could give police an indication of a criminal suspect’s ethnicity there and then thanks to a new bioassay.

Biological samples recovered at crime scenes can provide vital evidence to identify, accuse and exonerate. DNA/RNA analysis techniques for profiling suspects are sophisticated, but usually require complex equipment. On-site analysis of fluids is mostly limited to simple identification of possible samples, such as bloodstains, which are then collected and transported to specialist laboratories. This creates undesirable delays for investigations, where time is often of the essence.
