| 摘 要： | 利用硝酸银与铜之间发生置换反应原理,在铜箔上得到了有序的银纳米枝结构,用十二烷基磺酸钠(SDS)为表面活性剂,通过调控前驱体硝酸银的浓度,可在铜箔上得到不同密度的银纳米枝.表面拉曼增强实验结果表明,当分别以对巯基苯胺(4-ATP)、腺嘌呤和罗丹明G6为探针分子时,有序的银纳米枝结构比无序的银纳米粒子具有更好的拉曼增强活... |

| Abstract: | Ag dendrites were obtained on cleaned Cu plate via a simple galvanic displacement process between AgNO3 and Cu at room temperature, using sodiun dodecylsulfate(SDS) as surfactant. By the control of the concentration of precursor(AgNO3), Ag dendrites with different density were obtained. The performance of the Ag dendrites as surface enhanced Raman scattering(SERS) active substrate was evaluated by 4-aminothiophenol(4-ATP), adenine and Rhodamine G6 as the probe molecules. Compared with Ag nano particles(AgNPs) film, the SERS signal on Ag dendrites was obviously improved than on the AgNPs film. It is concluded that the Ag dendrites on Cu plate will be powerful SERS substrate for organic molecule and biological molecular detection. |
