Rapid in situ identification of arsenic species using a portable Fe3O4@Ag SERS sensor.
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.
