We report a highly sensitive and selective surface-enhanced Raman scattering (SERS)-based detection of aqueous Zn( ii ) ions (limit of detection 10 −14 M). Spectral changes for a silver nanoparticle-bound Raman reporter upon Zn( ii ) chelation constitutes the assay, which is applied to drinking wate...

Zusammenfassung:We report a highly sensitive and selective surface-enhanced Raman scattering (SERS)-based detection of aqueous Zn( ii ) ions (limit of detection 10 −14 M). Spectral changes for a silver nanoparticle-bound Raman reporter upon Zn( ii ) chelation constitutes the assay, which is applied to drinking water and to measurements of cellular uptake of Zn( ii ). HBA SERS peak frequency shifts in response to coordination are used to analyze the concentration of Zn( ii ) with ultra-high sensitivity.
