开发了支持金纳米线的聚碳酸酯（PC）微通道网络是一种活跃的微芯片。在拉曼横截面中观察到很大的增加，使我们能够收集由于裸露PC的荧光水平高而被拉曼技术可检测到的振动特征。与其他SERS实验相比，本研究依赖于在微观和纳米级水平上良好定义的电介质聚合物/金属表面的使用。该设备似乎是感测生物分子吸附的有前途的工具。
A polycarbonate (PC) microchannel network supporting gold nanowires was developed to be a SERS-active microchip. Observations of large increases in a Raman cross-section, allowed us to collect vibrational signatures which are not easily detectable by Raman techniques due to the high fluorescence level of bare PC. Compared to other SERS experiments, this study relies on the use of dielectric polymer/metal surfaces which are well defined at microscale and nanoscale levels. This device seems a promising tool for sensing the adsorption of biomolecules.
