A band that is strongly fluorescent and migrates electrophoretically with serum albumin is commonly found in electrophoretograms of sera from patients with chronic renal failure. We sought to determine whether the fluorescence originates from binding of certain still-unidentified metabolites or

Direct monitoring of primary molecular-binding interactions without the need for secondary reactants would markedly simplify and expand applications of high-throughput label-free detection methods. A simple interferometric technique is presented that monitors the optical phase difference resulting from accumulated biomolecular mass.
