摘要

我们提出了一种简单有效的纳米加工方法来生产大规模的三维纳米多孔银基SERS基板，该基板具有良好的空间再现性和EF约为108。我们的底物可以在没有任何表面功能化的情况下检测分散在水中的多环芳烃，LOD达到~ 20 nM。

Ultrasensitive Detection of Polycyclic Aromatic Hydrocarbons in Water Using 3D SERS Substrates produced in cold plasma

We present a simple and effective nanofabrication procedure to produce large-scale 3D nanoporous Ag-based SERS substrates which exhibit excellent spatial reproducibility and EF of about 108. Our substrates can detect polycyclic aromatic hydrocarbons dispersed in water without any functionalization of the surface, reaching a LOD of ~ 20 nM.
