Direct detection of fluoride ions in aquatic samples by surface-enhanced Raman scattering

We have developed a significant, efficacious, simple method with less synthetic steps for fluoride detection in water by using incorporating a molecular probe (DPP1) with a SERS-active substrate. This method used SERS to solve the problem of fluoride detection in water, which dramatically reduced the synthesis work. In contrast to the traditional colorimetric sensor assays, this method has a good detection limit and excellent performance.137
