Abstract

An assay for detecting an analyte which comprises applying a sample containing analyte to a surface of an absorbent material having at least one binder for the analyte supported on at least a portion of the surface. The absorbent material has a porosity which is capable of retaining non-charged particles having a size of at least 0.1 micron and no greater than 10 microns on the surface thereof. The sample flows past the binder and into the absorbent material. Porous plastics or ceramics are preferred absorbent materials.
