Abstract

Methods and kits for performing a two-phase optical assay for one or more than one analyte without intrinsic optical contrast in a sample are disclosed. The method requires use of a functionalized microparticle immobilized with two or more than functional components and an additional set of one or more than one functional component. The assay can be performed in one single container and does not need a wash step.
