Abstract :
Several different molecular film technologies have been developed for fabricating biosensors, including electrochemical codeposition of nonconductive polymer film and enzyme; electrochemical fabrication making a molecular interface of conductive polymer for an enzyme; and protein LB film fabrication. A microenzyme sensor for glucose was fabricated by electrochemical codeposition. An amperometric enzyme sensor was fabricated by incorporating the alcohol dehydrogenase-NAD-mediator system in a conductive polymer membrane. The protein LB film fabrication was used to produce an optical enzyme sensor for triglyceride.<>
