LABEL-FREE OPTICAL DETECTION IN CAPTURE ZONES IMMOBILIZED ON STRIPS FOR LATERAL FLOW ASSAYS

摘要

A test strip comprising a porous matrix, the test strip comprising a sample application zone for applying a liquid sample comprising an analyte; a reporter release zone, comprising a sensing material, the sensing material being adapted to selectively interact with the analyte by releasing an optical reporter, the reporter release zone being arranged downstream of the sample application zone; and a detection zone, comprising a capture material, the capture material being adapted to selectively bind the optical reporter and being arranged downstream of the reporter release zone..
