Luminol (Blood) Scientists can take advantage of the luminol reaction to locate potential blood evidence that would be undetectable through visual examination. The light, or luminescence, emitted in the luminol reaction is thought to result when an oxidizing agent, such as blood, catalyzes the oxidation of luminol by hydrogen peroxide in.

"I’ve always had a great interest in forensic science and I wanted my undergraduate research to reflect that," Camp said. During her internship at the LSP Crime Lab. it causes vibrations in water.

Lausanne – Scientists have outlined a new method using nanoparticles to detect fingerprints left at crime scenes. The new technology. coated with a carboxyl group made up of carbon, hydrogen and.

The Main Forensic Laboratory. The laboratory is equipped with a Dräger hydrogen gas detection system and a Simplex smoke detection system. The backs of the laboratory benches open onto aisles, which allow ready access to power, data, gas and vacuum pump utilities. All equipment is connected to the University’s network via personal computers.
