Fabrication of micro array of polyimide LB film and its application in bioelectronics device

초록

Ultra thin film of a polyamic acid having benzene and sulfonyloxyimide moieties was prepared using a Langmuir-Blodgett (LB) technique and micro array pattern of the photosensitive polyimide LB film was obtained by a UV lithographic method. To array cytochrome c along the micro array pattern, the well-characterized monolayer of cytochrome c was immobilized on a gold electrode surface by self assembly technique. The redox activity and electron transfer between cytochrome c molecular center and electrode interface for the self-assembled cytochrome c monolayer were investigated through the cyclic voltammetry measurements. Also, its application in bioelectronic device was discussed.
