Looking for biological stains

Looking for biological stains. Forensic scientist using an ultraviolet (UV) lamp to look for stains of biological origin, such as blood, sweat, semen or fingerprints. Biological materials often fluoresce (glow) under UV light, making them more visible. Sometimes a spray is used to add a chemical which will react with certain biological stains and make them more visible under UV light. The red lighting helps to make the fluorescence more visible. Once discovered, the stain can be analysed for DNA and other evidence to help link it to a suspect

EDITORS COMMENTS
In this print from Science Photo Library, we witness a dedicated forensic scientist on the hunt for biological stains. Equipped with an ultraviolet (UV) lamp, this male officer is meticulously scanning for traces of blood, sweat, semen or fingerprints that may hold crucial evidence in solving a crime. The use of UV light enhances visibility as biological materials tend to fluoresce or glow under its illumination. To further aid his search, the scientist employs a specialized spray that reacts with specific biological stains, making them even more prominent under UV light. The addition of red lighting intensifies the fluorescence and ensures no detail goes unnoticed in this dark room investigation. This image showcases the intersection between technology and criminal research as the scientist diligently examines each potential stain. Wearing protective goggles and equipped with cutting-edge equipment, he delves into the microscopic world of DNA analysis to establish connections between these elusive marks and potential suspects. The significance of his work cannot be overstated; by identifying these hidden clues, valuable evidence can be extracted from each stain. This invaluable information aids investigators in building strong cases against criminals while ensuring justice prevails. Science Photo Library's expertise shines through once again as they capture this pivotal moment where science meets law enforcement - an indelible testament to their commitment to providing exceptional visual resources for scientific exploration and discovery.
