Abstract
The present invention provides a method for detecting an analyte with high sensitivity. In the present method, a solution is supplied onto a substrate comprising a first electrode and a second electrode. Then, an alternating voltage is applied between the first electrode and the second electrode to aggregate, onto the surface between the first electrode and the second electrode by dielectrophoresis, bioparticles and dielectric particles contained in the solution. The aggregated bioparticles are broken to release the analyte contained in the bioparticles. The released analyte is bound to a first antibody and a second antibody to cause the dielectric particles to be immobilized onto the substrate through formation of a sandwich structure composed of the first antibody, the analyte, and the second antibody. Finally, the analyte is detected through the fluorescent substance contained in the immobilized dielectric particles.
