Electrochemical unit detecting biochemical molecules in fluid, includes electrodes coated with complementary biochemical molecules

摘要

Reference- (RE) and opposite electrodes (GE) are complemented by three or more working electrodes (AE1-3) in the vessel (1). The working electrodes are coated with biochemical molecules which are complementary to the biochemical molecules which are to be detected. Reference- (RE) and opposite electrodes (GE) are complemented by three or more working electrodes (AE1-3) in the vessel (1). The working electrodes are coated with biochemical molecules which are complementary to the biochemical molecules which are to be detected. A potentiostat (P) generates a given potential profile between the working electrodes and the reference electrode. Each of the working electrodes is connected to a current/voltage converter (S1-3) holding them at the same potential. An instrument measures current (AD) through the working electrodes. An Independent claim is included for the corresponding method.
