Abstract: The invention relates to an electrochemical sensor molecular bionics recognizing nanometer transduction membrane and the manufacturing method, which is a transduction membrane with special molecular bionics recognizing capability to template molecule and is characterized in that the transduction membrane is produced on the surface of the metal electrode of the electrochemical sensor molecular bionics, glass or quartz material and the transduction membrane is a membrane with controllable thickness in 5 to 50nm.The thickness of the transduction membrane is controlled by reversible addition-chain transfer free radical polymerization reaction time, and forms linear relation with time. The metal electrode is made of gold or platinum. The manufacturing method comprises conducting chlorsilane deriving, transferring the chlorsilane of the end surface of the optical fiber into chain transfer agent, then conducting molecular engram polyreaction to the optical fiber with the end surface of chain transfer agent, and finally eluting the template molecule in molecular bionics recognizing nanometer transduction membrane. The sensitivity of the sensor manufactured by the invention is high and the stability is good, which will be widely used in metallurgy, chemical industry, environment protection and other related fields.
