摘要

本文介绍了利用带有银枝晶的表面增强拉曼光谱(SERS)技术对罗丹明6G和一种爆炸性分子苦味酸进行痕量检测的低成本柔性滤纸衬底的研究工作。我们用一种简单的化学沉积方法合成了银枝晶。利用这些高支链结构的优势，我们可以分别检测浓度为1 pM和100 nM的R6G和苦味酸。

Flexible Paper Substrate with Silver Dendrites for Trace Detection of Dye and Explosive Molecules using SERS

We present here our work on low cost, flexible filter paper substrate with silver dendrites for trace detection of Rhodamine 6G and an explosive molecule, picric acid using surface enhanced Raman spectroscopy (SERS) with silver dendrites. We have synthesized silver dendrites by a simple method of electroless deposition. With the advantage of these highly branched structures, we could detect R6G and Picric Acid of concentrations 1 pM and100 nM, respectively.
