Luminol is a chemical compound (C2H7N3O2) that is oxidized by hydrogen peroxide and a metal that releases energy as light. Luminol is used to find traces of blood left at a crime scene. Blood contains a protein called hemoglobin that carries oxygen from the lungs to cells. Small amounts of iron in hemoglobin is sufficient to initiate the chemiluminescent between luminol and hydrogen peroxide ( Neil, Jayne and David, 2006). When it is first sprayed, it is clear and if blood particles were left behind then it will present a blue glow ( Robert Parker, 2016). The conclusions of the experiment are important for people such as investigators and victims, who are searching for a solution to a case and what happened.
