“…A colorimetric and surface-enhanced Raman scattering dual-signal sensor for Hg 2+ ions based on bismuthiol II-capped gold nanoparticles, has been proposed by Duan et al [257]. Such strategies have been applied for the detection of Pb 2+ [258,259] Zn 2+ [260], Ni 2+ [261], Cu 2+ [262][263][264], Cr 3+ [265], Co 2+ [263], As 3+ [266] and Ag + [259,267]. Ly and Joo [268] proposed a SERS sensor for Hg 2+ ions based on the selective changes in the Raman signals of poly-L-lysine at 458 and 1115 cm -1 , in contrast with other ions (Cr 3+ , Pb 2+ , Mn 2+ , Zn 2+ , Co 2+ , Ni 2+ , Cd 2+ , Fe 2+ , Na + , Ca 2+ , Mg 2+ , Cu 2+ , NH 4 + and Fe 3+ ).…”

Concerns over exposure to mercury have motivated the exploration of cost-effective, rapid, and reliable method for monitoring Hg 2+ in the environment. Recently, surface-enhanced Raman scattering (SERS) has become a promising alternative method for Hg 2+ analysis. SERS is a spectroscopic technique which combines modern laser spectroscopy with the optical properties of nano-sized noble metal structures, resulting in substantially increased Raman signals. When Hg 2+ is in a close contact with metallic nanostructures, the SERS effect provides unique structural information together with ultrasensitive detection limits.This review introduces the principles and contemporary approaches of SERS-based Hg 2+ detection. In addition, the perspective and challenges are briefly discussed.

“…A linear range of 2 × 10 −7 -2 × 10 −6 M for Hg 2+ was obtained. Similarly, Tan et al [123] reported an SERS sensor for multiple heavy metal ions based on 2-mercaptoisonicotinic acid modified Au NPs. Hg 2+ and Pb 2+ could be detected by using relative peak intensity ratios, with detection limits of 3.4 ×10 −8 and 1.0 ×10 −7 M, respectively.…”

Mercuric ion (Hg 2+ ), released from both natural and industrial sources, has severe adverse effects on human health and the environment even at very low concentrations. It is very important to develop a rapid and economical method for the detection of Hg 2+ with high sensitivity and selectivity. Nanomaterials with unique size and shape-dependent optical properties are attractive sensing materials. The application of nanomaterials to design optical sensors for Hg 2+ provides a powerful method for the trace detection of Hg 2+ in the environment, because these optical sensors are simple, rapidly responsive, cost-effective and highly sensitive. This review summarizes the recent advances on the development of optical assays for Hg 2+ in aqueous solution by using functionalized nanomaterials (including noble metal nanoparticles, fluorescent metal nanoclusters, semiconductor quantum dots and carbon nanodots). Detection strategies based on the Hg 2+ -induced changes in spectral absorbance, fluorescence intensity and surface-enhanced Raman scattering signals were described. And the design principles for each optical assay were presented. In addition, the future challenge and the prospect of the development of nanomaterial optical sensors for Hg 2+ detection were also discussed.
