A common method to test for blood is to spray an area with a solution of luminol and hydrogen peroxide. If blood is present, the iron atoms within the hemoglobin molecules in red blood cells act as a ...

From glowing luminol reactions to creating artificial logic gates, [Marb]—a self-proclaimed tinkerer—takes us step-by-step through crafting the building blocks for what might be the simplest ...

Peroxides act as an oxidizing agent. The luminol is converted to an excited-state product. This product decays to the ground state while emitting light. Luminol is 3-aminophthalhydrazide. Peroxide ...
