FABRICATION OF HIGH-PERFORMANCE TRANSDUCERS FOR FET-TYPE BIOELECTRONIC NOSES USING POLYPYRROLE NANOTUBES CONJUGATED WITH HUMAN OLFACTORY RECEPTORS

摘要

PURPOSE: A manufacturing method of an olfactory sense nano biosensor which combines the human olfactory receptor protein and a conductivity polymer nanofiber is provided to attach the human olfactory receptor protein which applies to the receptor to the 1D conductive polymer nano material, thereby providing unlabelled FET olfactory nano bio sensor. CONSTITUTION: An electrode substrate is a surface modified to amine radical. The conductivity polymer nanomaterial having functional group uses condensation reaction and is fixed to the electrode substrate which is surface-modified. As the olfactory receptor protein uses the condensation reaction, the conductive polymer nano material having the functional group fixed to the electrode substrates is attached. An electric signal according to the chemical/electrical characteristic change between a first and a second transistor uses a FET(Field Effect Transistor) array utilizing the nano biosensor medium and is detected.
