Abstract
Devices and methods for generating electrogenerated chemiluminescence, using an electrode which is coated with an immobilized layer of a compound capable of generating ECL. The coated electrode can be immersed along with a second electrode into an electrolyte solution containing a reactant which can react with the immobilized compound to generate ECL.
