| Surface-enhanced Raman spectroscopy (SERS) has been used as a highly-sensitive method for the detection of a wide variety of analytes. We are developing a method to detect arsenic anions using SERS on a gold-nanoparticle substrate. Phosphine-stabilized gold nanoparticles have been prepared and partially exchanged with amine-functionalized thiols, resulting in positively-charged nanoparticles. These particles will be analyzed for their ability to detect and differentiate various anionic arsenic species. |
