“…The enhancement effect of SERS substrate is mainly attributed to the localized surface plasmon resonance (LSPR) of the plasmonic materials [ 22 , 23 , 24 , 25 ]. With the development of nanotechnology, various plasmonic nanostructures have been developed and used for SERS sensing [ 24 , 26 , 27 ]. In order to detect analytes from objectives with irregular surfaces, flexible SERS substrates have been proposed.…”

The flexible SERS substrate were prepared base on regenerated cellulose fibers, in which the Au nanoparticles were controllably assembled on fiber through electrostatic interaction. The cellulose fiber was regenerated from waste paper through the dry-jet wet spinning method, an eco-friendly and convenient approach by using ionic liquid. The Au NPs could be controllably distributed on the surface of fiber by adjusting the conditions during the process of assembling. Finite-difference time-domain theoretical simulations verified the intense local electromagnetic fields of plasmonic composites. The flexible SERS fibers show excellent SERS sensitivity and adsorption capability. A typical Raman probe molecule, 4-Mercaptobenzoicacid (4-MBA), was used to verify the SERS cellulose fibers, the sensitivity could achieve to 10−9 M. The flexible SERS fibers were successfully used for identifying dimetridazole (DMZ) from aqueous solution. Furthermore, the flexible SERS fibers were used for detecting DMZ from the surface of fish by simply swabbing process. It is clear that the fabricated plasmonic composite can be applied for the identifying toxins and chemicals.

“…Recent studies mostly focused on the removal of MB but less on the simultaneous determination of MB and its metabolite residues in food [ 12 , 13 ]. Lately, various detection methods such as spectrophotometry [ 6 , 14 ], indirect competitive enzyme-linked immunosorbent assay (IC-ELISA) [ 15 ], resonance light scattering (RLS) [ 16 ], liquid chromatography (LC) [ 8 ], and liquid chromatography–tandem mass spectrometry (LC–MS/MS) [ 17 , 18 ] for MB and its metabolite residues in aquatic products have been developed. As the LC method is sensitive, rapid, and accurate, it has become the most used method for the detection of MB in food.…”

“…Yu et al established a new LC–MS/MS method for the determination of MB and its metabolite residues in fish tissue with an LOQ of 2.0 µg/kg [ 19 ]. In addition, Xu et al [ 14 ] developed a surface-enhanced Raman spectroscopy (SERS) method to detect MB in four fish tissues with the limit of detection (LOD) of 1–5 µg/kg. Methods for the analysis of phenothiazine dyes in animal tissues have been limited to MB and AZB.…”

A sensitive and reliable method was developed to determine methylene blue (MB) and its metabolite residues, including azure A (AZA), azure B (AZB), and azure C (AZC) in aquatic products by HPLC–MS/MS. The samples were extracted by acetonitrile and cleaned up by alumina-neutral (ALN) cartridges. The analytes were separated on a Sunfire C18 column (150 mm × 2.1 mm, 5 µm). The method was validated according to the European criteria of Commission Decision 2002/657/CE. Good linearity between 1–500 µg/L was obtained with correlation coefficients (R2) greater than 0.99. The limit of quantification (LOQ) was 1.0 µg/kg. The average recoveries at three levels of each compound (1, 5, and 10 µg/kg) were demonstrated to be in the range of 71.8–97.5%, with relative standard deviations (RSDs) from 1.05% to 8.63%. This method was suitable for the detection of methylene blue and its metabolite residues in aquatic products.

“…Dyes are widely used in the leather, paper, pharmaceutical, plastic, and textile industries [ 15 , 16 ]. Emissions of large amounts of dyes in wastewater can negatively affect natural aquatic systems and ecosystems and can affect human health if the dye is transferred through the food chain [ 17 , 18 ].…”

“…Emissions of large amounts of dyes in wastewater can negatively affect natural aquatic systems and ecosystems and can affect human health if the dye is transferred through the food chain [ 17 , 18 ]. Some dyes are poorly degradable in the environment and potentially toxic, so have been prohibited from being used in or emitted to areas used for aquaculture in many countries [ 16 ]. Methylene blue (MB) is one of the most commonly used dyes.…”

Tiny changes in the mass of the sensor in a quartz crystal microbalance with dissipation monitoring (QCM-D) can be observed. However, the lack of specificity for target species has hindered the use of QCM-D. Here, molecularly imprinted polymers (MIPs) were used to modify a QCM-D sensor to provide specificity. The MIPs were formed in the presence of sodium dodecyl benzene sulfonate. Imprinted layers on Fe3O4 nanoparticles were formed using pyrrole as the functional monomer and cross-linker and methylene blue (MB) as a template. The MIPs produced were then attached to the surface of a QCM-D sensor. The MIPs-coated QCM-D sensor could recognize MB and gave a linear response in the concentration range 25 to 1.5 × 102 µg/L and a detection limit of 1.4 µg/L. The QCM-D sensor was selective for MB over structural analogs. The MIPs-coated QCM-D sensor was successfully used to detect MB in river water and seawater samples, and the recoveries were good. This is the first time MB has been detected using a QCM-D sensor. Mass is an intrinsic property of matter, so this method could easily be extended to other target species by using different MIPs.
