| 摘 要： | 将L-半胱胺酸修饰到金电极表面,通过循环伏安法、阻抗法进行表征。在pH低时,高频部分的半圆的半径较pH高时的要大,其原因可能跟探针离子与L-半胱胺酸的静电作用有关。

| Abstract: | L-cysteine is modified onto the surface of the gold electrode. The L-cysteine modified gold electrode is characterized by the method of the cyclic voltammetery (CV) and of electrochemistry impedance spectroscropy (EIS). Radius of the semicircles in the part of the high frequency zone at low Ph value is larger than that at high Ph value and perhaps because of the static effect of probe and L-cysteine. |
