Luminol – in crime scene

Luminol - in crime scene

Saranya Naveen Kumar

Luminol – an organic compound emits light when it is oxidised and a phenomenon known as chemiluminescene. This reaction shows similar effects, where fireflies uses to emit light and in glow-sticks and some roadside emergency lights.

Chemiluminescence have the potential for low detection limits and wide linear calibration ranges. Both are sensitive to environmental conditions (solvent type, the presence of quenchers, pH, ionic strength, and temperature) that may alter the quantum efficiency of emission.

The luminescene emitted in this reaction is thought to result when hydrogen peroxide in a basic solution oxides with luminol in the presence of an oxidising agent such as blood.

Forensic scientists uses Luminol in the place of crime scenes as to detect invisible blood stains. It glows when luminol touches blood and it glows, thus help in photography.

“Current study says that luminol which is being used at crime scenes can kill the malaria parasite Plasmodium falciparum present in blood cells”.
