Abstract: Gaseous elemental mercury (GEM�Hg 0 (g) ) is a highly toxic global pollutant with environmental and human health effect concerns. Monitoring the GEM released in gold mining operation regions is extremely necessary. Herein, we develop an indirect surface-enhanced Raman scattering (SERS)-miniaturized sensor for the direct detection of Hg 0 (g) using gold nanorods (AuNRs) and rhodamine 6G as a probe molecule. SERS spectra show a suppressed signal after exposure to Hg 0 (g) in different concentrations caused by th… Show more
