Analytes can be trapped within the plasmonically-active nanogaps of gold nanoparticle monolayers and produce very strong surface enhanced Raman (SERS) signals due to enhanced optical fields in the gaps. Trace amounts of molecules can be detected and identified, with detection limits often in the single molecule regime. This project aims to develop this sensing technique for qualitative and quantitative continuous environmental monitoring to test for harmful airborne and aqueous pollutants.

分析物可以被捕获在金纳米颗粒单分子膜的等离子体活性纳米GaP中，并由于间隙中增强的光场而产生非常强的表面增强拉曼(SERS)信号。可以检测和识别痕量分子，检测极限通常在单分子区域。该项目旨在开发这一传感技术，用于定性和定量的连续环境监测，以测试有害的空气和水中污染物。
