University at Albany associate professor of chemistry Igor Lednev has developed a novel, easy-to-use approach for crime scene investigators (CSIs) to identify body fluids at crime scenes. Utilizing Raman spectroscopy, Lednev's approach will allow investigators to quickly make on-field, confirmatory identifications of body fluids. The portable spectrometers -- devices used to measure properties of light over a specific portion of the electromagnetic spectrum -- will be capable of differentiating between human and animal species, and determining the age of a biological stain.
