Abstract

A test strip comprising a porous matrix, the test strip includes a sample application zone for applying a liquid sample including an analyte; a reporter release zone, having 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, having a capture material, the capture material being adapted to selectively bind the optical reporter and being arranged downstream of the reporter release zone.
