Abstract:
본 발명은 아스코르빅 산의 영향을 받지 않고, 도파민을 선택적으로 검출할 수 있는 금 나노입자가 분산된 과산화 전도성 고분자 나노선의 다이아몬드 박막 전극을 이용한 전기화학 센서를 제공한다. 본 발명에 따른 센서는 0.15 내지 500 μM에 이르는 넓은 농도범위 내에서 선형성을 보이며, 0.131μA/μM의 높은 감도와 0.03μM의 낮은 검출한계를 보이며 도파민을 감지할 수 있다.
Abstract:
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.
