Date Jul. 9, 1998An apparatus for detecting an analyte in a sample, including a cell with at least one fixed electrode, at least one mobile electrode opposite the fixed electrode, the mobile electrode being configured to move with respect to the fixed electrode, and a sample receiving cavity defined by a space between the fixed electrode and the mobile electrode, wherein a surface of at least one of the fixed electrode and mobile electrode facing the sample receiving cavity is configured to bound a ligand of the analyte to be detected. The apparatus also includes a displacement mechanism configured to move the mobile electrode; and an external circuit connected to the fixed electrode and to the mobile electrode, and configured to measure a parameter having a value depending on the presence between the fixed electrode and the mobile electrode of the analyte to be detected.
