DOPAMINE DETECTION SENSOR USING A DIAMOND THIN FILM ELECTRODE OF HYDROGEN CONDUCTIVE POLYMER NANO WIRES IN WHICH GOLD NANO PARTICLES ARE DISPERSED, CAPABLE OF DETECTING DOPAMINE SELECTIVELY WITHOUT BEING INFLUENCED BY ASCORBIC ACID

摘要

PURPOSE: A Dopamine detection sensor using a diamond thin film electrode of hydrogen conductive polymer nano wires in which gold nano particles are dispersed is provided to show linearity in a wide range of density, and to detect Dopamine as showing high sensitivity and low detection limit.;CONSTITUTION: A Dopamine detection sensor using a diamond thin film electrode of hydrogen conductive polymer nano wires in which gold nano particles are dispersed includes a working electrode, a counterpart electrode and a reference electrode. The counterpart electrode is formed with a platinum wire. The reference electrode is formed with silver and silver chloride. The working electrode is a Boron-doped diamond (BPD) thin film electrode. Conductive polymer combined through electrolytic polymerization reaction is included in the surface of the thin film electrode. Gold nano particles are coated in the conductive polymer.;COPYRIGHT KIPO 2013
