Patent Title: Bionic molecular recognition nano sensing film of optical fibre sensor and method for producing the same
Publication date: 2008
Publication number: CN101196462

Abstract: A molecular bionics recognizing nanometer transduction membrane of optical fiber sensor and the manufacturing method are provided, 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 end surface of the silicon optical fiber of Sio2, 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 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 invention composes molecular engram nanometer transduction membrane, which makes the thickness of the transduction membrane reach nm grade. The sensitivity is high and the stability is good, which will be widely used in metallurgy, chemical industry, environment protection and other related fields.
