Abstract:
1. A biochip for detecting a biomolecule electrically comprising: a first plate that has a plurality of sensing electrodes; a second plate that forms a space of a reaction chamber with respect to the first plate by being combined with the first plate in a predetermined distance; and wherein the second plate forming the space of the reaction chamber is perforated to have a fluid inlet in the direction of thickness and further perforated to have a fluid outlet in the direction of thickness on the opposite side of the fluid inlet; the inlet and the reaction chamber, and the outlet and the reaction chamber are communicated with each other to allow fluid to flow therethrough in the reaction chamber; and a reference fluid having a high dielectric constant, a reaction solution and a target sample are introduced through the inlet, and the reference fluid having a high dielectric constant, the reaction solution and the target sample flow outside through the outlet.
