Solving crimes with chemiluminescence

Blood is a key piece of evidence

Perpetrators of a crime may go to great lengths to clean, conceal and otherwise rid surfaces of this tell tale sign of foul play. But despite a criminal’s best efforts, blood may still remain even if it’s not visible.

Luminol literally brings this evidence to light, emitting a blue glow wherever trace amounts of blood may remain.

When luminol is activated with an oxidant, the solution reacts with the iron in blood. The energy created by this reaction is emitted as a blue light—chemiluminescence.
