Two solutions are combined in a darkened room, producing luminescence that lasts for several seconds. Peroxides act as an oxidizing agent. The luminol is converted to an excited-state product. This ...

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 ...

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 ...
