ENZYME ANALYSIS SYSTEM AND ANALYSIS BY SAID SYSTEM

摘要

PURPOSE:To obtain an analysis system which can make measurement with high-speed response and high sensitivity even with a slight quantity of sample by using a microelectrode of a biofunction material. CONSTITUTION:The microelectrode 1 having a biofunction is the electrode having a conductive fine particle material layer formed by impregnating the biofunction material such as enzyme on the surface of a very small electrode and is produced by electrodepositing the biofunction material directly on the section of a platinum wire or the like and electrolytically reducing a metal salt simultaneously to deposit the conductive fine particle material together with the biofunction material thereon. A micro device 6 is constituted by using this microelectrode as a working electrode 1, a platinum wire as a counter electrode 2 and silver chloride as a reference electrode 3. The microelectrode 1, the counter electrode 2 and the reference electrode 3 are solidified and fixed into a hole of a 'Teflon(R)' resin 5 by a resin 4. The measurement and detection are made with the rapid response and high sensitivity by using such microelectrode.
