The traditional Chinese medical acupuncture therapy is widely spread over the world now.The meridian theory.as the theoretical basin for the traditional Chinese medicine.has directed the manipulating for a long time.In order to made the theory compatible with modern medical sciences,a novel biosensor which is of the characteristic of the traditional Chinese medical acupuncture needle and the tissue-based carbon paste microelectrode has been developed.The biosensor.which is both an actuator and a sensor,is employed to the acupuncture therapy as well as the detection of neurotransmitter-dopamine(DA).The construction of the biosensor is that a stainless steel hollow sensing needle(i.d.=200μm) which has several small holes is filled with spinach tissue-based carbon pastes that connect with a copper wire as a conductor.The detection limit reaches 10 mol/L and the life time one month.In vitro characterization experiments have shown the biosensor’s performance acceptable.The biosensor is also used in the ini The traditional Chinese medical acupuncture therapy is widely spread over the world now.
