Question

Quizplus · Accepted Answer

Luminol is a chemical that reacts with the iron in hemoglobin, an oxygen-carrying component of blood, causing it to emit a blue glow. This property makes it useful for detecting trace amounts of blood at crime scenes, even if the blood has been cleaned or is not visible to the naked eye. Importantly, the use of luminol does not destroy DNA, which allows for subsequent DNA analysis of the detected blood traces.
