Luminol is a chemical substance that emits a very intense blue light, called chemiluminescence. In order to emit this light, the luminol must be placed in contact with an activator, such as hydroxide or hydrogen peroxide, or a catalyst such as copper, iron, or cyanide. The resulting chemical reaction causes the production of a bluish light. The most well-known utilization of luminol is at crime scenes, where it reveals traces of blood which are invisible to the naked eye.
