Abstract: A microporous substrate for detection of surface bound target analyte molecules includes a microporous substrate material having opposed surfaces and tapered micropores extending through the substrate with the micropores having wider openings on one side of the substrate compared to the other side. The micropores have bound therein analyte specific receptors complementary to the target molecules. When a liquid sample containing the target analyte molecules with optical probes attached to the target molecules is flowed through the substrate, they bind to their complementary analyte specific receptors and emit light. This microporous substrate structure gives an increase in the collection efficiency of light emitted from optical probes when the light is detected by a light detector spaced from the side of the microporous substrate facing the larger micropores openings compared to a light collection efficiency of light emitted from the optical probes when the micropores are straight and not tapered.
