Abstract
Compounds which are useful as substrates for enzymes are disclosed. An enzyme-controlled process is provided for generating a colored species from an initially substantially colorless material as a result of enzymatic attack. The process can be exploited to provide an enzyme-amplified diagnostic assay method to detect an analyte of interest present in a test sample.
