BIO-SENSOR AND METHOD FOR DETECTING LOW MOLECULAR WEIGHT BIOMOLECULES AND NON-CHARGED BIOMOLECULES BY USING THE BIO-SENSOR

摘要

PURPOSE: A bio sensor and a method for detecting bio molecules are provided to electrochemically detect a target molecules having small molecular weight. CONSTITUTION: A bio sensor for detecting a target molecule comprises: a sensing unit on which target molecules for detecting on the surface; and a fluid channel for supplying analysis solution containing the probe molecules to a target molecules. The probe molecules specifically bind to target molecules. The probe molecules have larger charge than the target molecules.
