Luminol How long does the reaction last and can you redo the reaction by adding more blood? And does the reaction create electricity/energy? Asked by Nsp6115 on 25 Jul 08:31 Last updated by anonymous on 26 Dec 23:15
The reactant in Luminol is the reaction to the iron in the hemoglobin in blood. So, theoretically, more blood, more reaction. Luminol can be used on bloodstains that are as old as 3 years or more.
