“…The method exhibited high sensitivity with a LOD of 0.72 ppb. [64] In addition, SERS methods, for the analysis of other heavy metals in the environment using a portable Raman spectrometer, have also been developed, such as zinc ion (Zn 2+ ), [65] arsenic(III), [66] lead(II) [67] etc. used increasingly to prevent and treat various diseases in fish with the rapid development of aquaculture.…”

Recently, the surface‐enhanced Raman spectroscopy (SERS) technique emerges as a potential promising analytical tool for rapid, sensitive, and selective detection which can provide unique information about the substances in the presence of plasmonic nanostructures via finger‐printing SERS spectra. The progress in nanostructure SERS substrates and portable Raman spectrometers will promote this novel detection technique to play an important role in the future rapid on‐site assay. In this review, we summarized the latest research on SERS detection technique combined based on nanostructure SERS‐active substrates with portable Raman spectrometers and their potential on‐site detection applications in environment pollutants, agricultural pollutants, biomedical analysis, and other newly emerging fields (focusing particularly on the last 5 years of research). The future perspective of SERS for on‐site analysis is also discussed.

“…Recently, Ge et al developed a portable and simple method for the selective determination of As( iii ) in the field based on the SERS signal of As( iii )–O vibrations. 63 To improve the method's ability to detect As( iii ), phosphate was introduced as a coagulant. A phosphate buffer containing As( iii ) was first prepared and mixed with phosphate-mediated Ag colloids to investigate the effect of pH on the Raman signal performance.…”

“…High-Performance Liquid Chromatography (HPLC) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) are the traditional methods, with the limit of detection (LOD) down to microgram levels or less [ 6 ]. Likewise, atomic fluorescence spectroscopy [ 7 ], gold-nanoparticle colorimetric detection [ 8 , 9 ], and Surface-Enhanced Raman Scattering (SERS) [ 10 ] are other candidates that can achieve high precision and sensitivity at the expense of a trade-off. However, these highly expensive methods make regular and near real-time field monitoring of arsenic levels infeasible.…”

In this work, we report a low-cost and highly sensitive electrochemical sensor for detecting As(III) in water. The sensor uses a 3D microporous graphene electrode with nanoflowers, which enriches the reactive surface area and thus enhances its sensitivity. The detection range achieved was 1–50 ppb, meeting the US-EPA cutoff criteria of 10 ppb. The sensor works by trapping As(III) ions using the interlayer dipole between Ni and graphene, reducing As(III), and transferring electrons to the nanoflowers. The nanoflowers then exchange charges with the graphene layer, producing a measurable current. Interference by other ions, such as Pb(II) and Cd(II), was found to be negligible. The proposed method has potential for use as a portable field sensor for monitoring water quality to control hazardous As(III) in human life.
