Abstract

Rapid and sensitive SERS identification and quantification of arsenic species in multiple matrices have been realized using a Fe₃O₄@Ag magnetic substrate. The molecular structure of arsenic on Fe₃O₄@Ag characterized using EXAFS spectroscopy and DFT confirms the existence of a chemical effect on SERS enhancement.
