| 摘 要： | 利用电化学伏安方法和表面增强拉曼光谱(SERS)技术研究了在-1.0V~0V的电位区间内胞嘧啶在粗糙银电极和金电极表面上的吸附行为。结果表明,在所研究的电位区间,胞嘧啶通过N3位垂直吸附在粗糙银和金电极表面,且当电位负移时吸附作用减弱。

| Abstract: | This paper combined the electrochemical cyclic voltammetry and the SERS technique to study the adsorption behaviors of cytosine on roughened silver and gold electrodes from -1.0 V to 0 V. The SERS results indicate that cytosine adsorbed perpendicularly via the N3-end on roughened silver and gold electrodes. The adsorption interaction becomes weak with the negative movement of the potential. |
