摘要:

以滤纸的多级纤维结构为基底, 通过物理气相沉积(PVD)方法蒸镀一定厚度的银膜, 制备了表面增强拉曼试纸, 以罗丹明6G(R6G)为探针分子, 其最低检测限(LOD)可以达到10-10 mol/L. 采用密闭氮气环境保存可解决银SERS基底使用寿命短的问题, 使得试纸可以长时间保持活性.

Abstract:

Based on connatural hierarchical micro/nanostructures of filter paper, convenient and efficient surface-enhanced Raman scattering(SERS) test strips were prepared by coating a silver layer on paper through simple physical vapor deposition(PVD). The limit of detection(LOD) over the SERS test strip is 10-10 mol/L with the Rhodamine 6G as probe molecule. Placing the test strips in airtight N2 atmosphere could remain the activity for a long time.

Key words: Surface-enhanced Raman scattering(SERS) test strip, Silver, Physical vapor deposition(PVD), Quality
