We have realized a cloned enzyme donor immunoassay (CEDIA) on a microchip in 96 s. CEDIA is a homogeneous immunoassay, based on the bacterial enzyme β-galactosidase, which was genetically engineered into two inactive fragments: an enzyme donor and an enzyme acceptor. A model analyte was theophylline, and the detectable concentration range was from 0 to 40 μg mL-1. Our CEDIA using a microfluidic device was very simple and rapid, unlike microchipbased heterogeneous immunoassays and CEDIA on a well-type microchip.
