“…Particularly for MG, it was the number one illegal drug found in fish and fish products in the past ten years, based upon the database of the Rapid Alert System for Food and Feed of European Union [30]. In our previous study, we were able to detect MG and CV at concentrations as low as 0.1 ng/mL using Au–Ag core–shell (Au@Ag) bimetallic nanoparticles [31], which is much more sensitive than that using two commercial SERS substrates and as-obtained Au nanospheres [18,19,20,21,22]. However, because of the effect of sample matrices, the sensitivity for the detection of MG in actual fish muscle could be decreased by as much as 20 times compared to that in standard solutions [22].…”

“…SERS methods could be sensitive, easy-to-use, and affordable, serving as a good alternative to the more complicated and expensive chromatographic method. Our group’s previous studies involving the use of commercial SERS substrates and lab-synthesized Au nanospheres as SERS substrates led to less ideal results in sensitivity: the lowest detectible concentrations for standard solutions were 0.5–700 ppb for MG, 0.5–50 ppb for CV, and 0.8–5 ppm for furazolidone [18,19,20,21,22]. This study is a continuation of our previous work on the development of more sensitive SERS approaches for the detection of banned fish drugs.…”

Surface-enhanced Raman scattering or surface-enhanced Raman spectroscopy (SERS) is a promising detection technology, and has captured increasing attention. Silver nanowires were synthesized using a rapid polyol method and optimized through adjustment of the molar ratio of poly(vinyl pyrrolidone) and silver nitrate in a glycerol system. Ultraviolet-visible spectrometry, X-ray diffraction, and transmission electron microscopy were used to characterize the silver nanowires. The optimal silver nanowires were used as a SERS substrate to detect prohibited fish drugs, including malachite green, crystal violet, furazolidone, and chloramphenicol. The SERS spectra of crystal violet could be clearly identified at concentrations as low as 0.01 ng/mL. The minimum detectable concentration for malachite green was 0.05 ng/mL, and for both furazolidone and chloramphenicol were 0.1 μg/mL. The results showed that the as-prepared Ag nanowires SERS substrate exhibits high sensitivity and activity.

“…The most widely used commercial substrate, Klarite™ (Renishaw Diagnostics Ltd., Glasgow, UK), has a gold‐coated surface consisting of a regular pattern of inverted square pyramid subunits (Perney et al., ). Klarite has been on the market for more than 10 years and applied for detection of melamine (He et al., ), TBHQ (Pan et al., ), pesticides such as phosmet and carbaryl (Fan et al., , ), and banned and restricted drugs including chloramphenicol (Li et al., ), sulfamerazine (Li et al., ), furazolidone (Zhang et al., ), crystal violet (Li et al., ), and malachite green (Zhang et al., ; Zhang et al., ) in various foods. For colorants including crystal violet and malachite green, as low as single‐digit ppb levels could be detected due to the additional molecule resonance or SERRS effect using this substrate; but for noncolorant compounds, the detectible minimum concentration is normally around 0.1 to 10 ppm.…”

Surface‐enhanced Raman spectroscopy (SERS) provides a potential solution for rapid analysis of trace compounds such as residual pesticides, naturally occurred toxicants, banned or restricted drugs, and food additives in complex food matrices. In this review, the basic principles of SERS and general approaches to successfully apply SERS in food analysis are covered from an applications perspective. The key steps including substrate selection and evaluation, sample preparation and simplification, spectral collection, and data analysis during the development of SERS methods for food analysis are summarized, together with the discussion of typical underlying technical barriers or major challenges of these methods and their applications. Future directions in successfully applying SERS technology as a routine analytical approach to solve real‐world food problems are analyzed. This comprehensive review summarizes the recent progress on theory, application, and scope of SERS for food analysis, providing a basic understanding of the technology; more importantly, key methodology, potential pitfalls, and possible solutions during the development of rapid SERS methods based on authors’ years of SERS experience are shared with researchers in the field.

“…In recent years, there have been some reports about the alkaline hydrolysis of MG [21][22][23][24][25], by biosorption [26,27,] or sonochemical method [28,29,].Many researchers have shown that the effects on dyes faded reactions in alkaline or acidic environment of micelles can be attributed to electrostatic, hydrophobic interactions [30][31][32][33][34][35], isomerization, or solvation effects [36,37,]. Although there were some researches on the alkaline fading of MG in the presence of surfactants, studies on thermodynamics and kinetics direct interactions between MG and surfactants still need to be continued.…”

The absorption spectrum of malachite green (MG) in a series of aqueous solutions with surfactant octylphenol polyoxyethylene ether (10) (OP-10) has been determined by the UV-Vis spectrophotometer. The association interaction between the MG and non-ionic surfactant OP-10 in aqueous solutions resulted in obvious fading of MG. We established the thermodynamics model of association between MG and OP-10, and determined the association equilibrium constant in aqueous solutions. By measuring the absorbance of a series of aqueous solutions which have different molar concentrations of OP-10 but same concentration of MG at different time points, the order and rate constants of association reactions were determined and the reaction kinetics equation was set up.
