How Luminol Works

Product Details

When it comes to Luminol, it may not be unfamiliar to everyone. It often appears in detective dramas with murder scenes. Most of the Luminol that appears in TV dramas is liquid. In fact, Luminol's original shape is a light yellow powder, which needs to be mixed with hydrogen peroxide in a certain proportion to form a solution. Therefore, the Luminol reagent we see in TV dramas is not pure Luminol.

Secondly, in TV dramas, a dark environment is usually chosen for Lumino testing. This is because Lumino emits bright blue fluorescence when detecting bleeding marks, but the time is relatively short. Therefore, a dark environment is easier to observe changes in fluorescence and take photos. The detection of Luminol is very sensitive, fast, and convenient. No matter how small or long separated the blood stains are, there is no escape under the Luminol reagent.

So, how does Lumino work? Firstly, we all know that blood contains hemoglobin, which contains iron. Iron can catalyze the decomposition of hydrogen peroxide in luminol reagent into water and monooxygen, which can oxidize luminol and make it glow; Secondly, hemoglobin is responsible for transporting oxygen, so a large amount of oxygen can also catalyze the reaction between hydrogen peroxide and luminol, causing blood stains to emit light.

In addition, animal blood, animal or human excreta, and hypochlorite bleach can all make Luminol glow, but these factors will not interfere with Luminol's detection of human blood stains. Lumino reacts with blood and does not damage the DNA in the bloodstains. Modern technology can quickly distinguish between human bloodstains or other traces.
