ABSTRACT

Electrogenerated chemiluminescence (ECL) is a branch of luminescence initiated by electrochemical reactions. It combines analytical electrochemistry and luminescence spectroscopy. This entry intends to first discuss briefly the fundamentals of ECL, its unique features with respect to other luminescence, and mechanisms of typical ECL systems. This will be followed by a general description of ECL instrumentation. Finally, ECL applications with emphasis on the detection of biomolecules will be presented.
