버얼리종 담배에서 추출물에서 얻은 peroxidase와 다중벽 탄소 나노튜브를 이용한 dopamine 정량바이오센서를 만들었다. Peroxidase는 dopamine을 dopamine quinone으로 산화시키는 반응의 촉매 역할을 한다. 이 논문은 효소의 농도, pH와 같은 바이오센서의 감응에 영향을 주는 parameter를 조사하였다. 또한, 전극의 감도, 직선성의 범위, 전극의 안정성을 조사하였다. 본 실험에 사용한 dopamine의 정량 센서는 pH 6.50, 0.010 M 인산 완충용액, -0.15 V의 가해준 전압에서 가장 좋은 감응을 나타내었다. 전극의 검출한계(S/N = 3)는 2.7×10−6 M이었으며, 5.0×10−2 M dopamine을 이용하여 10회 반복 측정한 상대표준편차는 1.3%이었다.
The development of an enzymatic biosensor for dopamine determination based on multiwall carbon nanotubes (MWCNTs) and peroxidase obtained from the crude extract of burley tobacco (Nicotiana tabacum L.) was proposed. Peroxidase catalyzes the oxidation of dopamine to dopamine quinone. The influence on the response of analytical parameters of biosensors such as enzyme concentration, dopamine concentration, pH, and phosphate buffer solution concentration were investigated. The analytical parameters obtained, including sensitivity, linearity, and stability, were investigated. The proposed method for dopamine determination presented good selectivity even in the presence of uric acid and ascorbic acid. The sensor presented a higher response for dopamine in 0.010 M phosphate buffer at pH 6.50, with an applied potential of -0.15 V. The detection limit of the electrode was 2.7×10−6 M (S/N = 3) and the relative standard deviation of the measurements, which were repeated 10 times using 5.0×10−2 M dopamine, was 1.3%.
