Claim:
1. A device for the qualitative and/or quantitative detection of analytes, comprising: a reaction chamber formed within a chamber body between a first surface and a second surface, wherein the second surface is located opposite to the first surface, and wherein the distance between the first surface and the second surface is variable; a porous matrix located in the reaction chamber between the first surface and the second surface, wherein the porous matrix is reversibly compressible; and the porous matrix is a support member comprising a set of capture sites comprising multiple capture sites, the multiple capture sites disposed in a compressible medium in three dimensions about the member and together occupying a total volume, each of the capture sites capable of capturing a detectable label in the presence of a common analyte, the support member configured to accommodate a liquid mixture in contact with the capture sites, the liquid mixture comprising the detectable label and the analyte; an actuator configured to decrease the total volume occupied by the capture sites and remove at least a portion of the liquid mixture from the support member; a reservoir adjacent to the porous matrix that receives displaced liquid and comprises at least one expandable member that expands upon receiving displaced liquid; and a detector configured to determine the presence of captured detectable label attached to the support member when the capture sites are in the decreased-volume state, wherein a part of the reaction chamber is made of electrically conductive material.
