Overview

The detection, collection, and analysis of blood evidence recovered from a crime scene is critical in a forensic investigation because of the potential DNA it carries. However, crime scenes are often chaotic, and biological fluids can be hard to locate. With the support of the National Institute of Justice (NIJ) funding, chemist Stephen Morgan, PhD, and his team at the University of South Carolina in Columbus, SC, developed a prototype thermal infrared (IR) camera that can rapidly and selectively identify blood stains in ambient lighting without the use of reagents. The camera, which can be operated by a person with minimal technical knowledge, highlights blood stains by filtering out wavelengths that are not characteristic of blood proteins.

“This technology provides the ability to detect blood in all sorts of circumstances, even in some cases where traditional techniques can’t.”
