Abstract
What is described are methods and apparatus for performing a binding assay for an analyte of interest present in a sample. The methods include the steps of: forming a composition containing said sample, an assay-performance-substance which contains a component linked to a label compound capable of chemiluminescing when triggered, and a plurality of coated magnetic particles capable of specifically binding with the analyte and/or said assay-performance-substance; incubating said composition to form a complex which includes a particle and said labeled component; magnetically collecting said complex at the surface of an electrode; inducing said label to luminesce by contacting it with a trigger, said trigger being formed in-situ by conversion of a precursor molecule upon introduction of electrochemical energy; and measuring the emitted luminescence to measure the presence of the analyte of interest in the sample.
