NANOPOROUS MEMBRANE IMMUNOSENSOR

摘要

A sensor for a selected analyte in a test sample has according to figure 1: (a) a semipermeable membrane (10) with pores (16) for retaining the analyte, where the membrane (10) has been chemically modified by attachment of membrane modifiers (12); (b) immunoassay labels which have label binding ligands where these label binding ligands will have a binding affinity for the membrane modifiers (12) in the presence of the analyte, and a measurably different binding affinity for the membrane modifiers in the absence of the analyte; and (c) a label detecting system, for detecting the presence of the labels on the membrane (10).
