“…To investigate the potential of the AgNPs/PVA@Ag nanofibers platform in practical application, the SERS detection for MG molecule, a chemical of poisonous triphenylmethane [34,35], was carried out. As shown in Figure 7A, the typical Raman peaks of MG at 1179, 1372, and 1625 cm −1 have a sharp form at high concentration of 10 −5 m. The band intensity weakens with the decrease of the MG concentrations and the main characteristic peaks such as 1372, 1595, and 1625 cm −1 could be observed at concentration lower down to 10 −9 m. Moreover, the linear fit calibration curve (R 2 = 0.977) with error bars (same batch but different positions) is illustrated in Figure 7B.…”

An efficient electrospun aligned surface enhanced Raman scattering (SERS) and maize-like substrate of polyvinyl alcohol (PVA) composite and Ag colloid nanofibers decorated with thermal evaporated Ag nanoparticles (AgNPs) has been developed by taking advantage of electrostatic interactions. The synergistic effects of the evaporated AgNPs (niblets) and the Ag colloid in PVA (corncob) could arouse strong electromagnetic field between the lateral and vertical nanogaps which has been demonstrated by experiment and finite-different time-domain (FDTD) simulation. In this experiment, the aligned nanofibers possesses an excellent sensitivity by detection of crystal violet (CV) and malachite green (MG) molecule at low concentration. Moreover, the proposed flexible SERS sensor was measured with outstanding uniformity and reproducibility. We also carried out in-situ electrospinning on a curved surface to detect the mixture of Sudan I, CV and MG molecule, which demonstrates that flexible SERS sensor, has enormous potential in accurate and in-situ detection on the complex geometric structure.

“…Moreover, because of its adverse effects on water breeding products, several methods have been developed to detect MG. These include techniques such as adsorptive stripping voltammetry [ 4 ], high-performance liquid chromatography (HPLC) [ 5 ], immunoassays [ 6 ], mini-column extraction [ 7 ], molecular imprinting [ 8 , 9 ], and surface-enhanced Raman spectroscopy (SERS) [ 10 ]. In a study by Sun [ 11 ], a PMMA (polymethyl methacrylate)/Ag/graphene/Ag/graphene substrate was used to detect MG with a sensitivity of 10 −7 M. Moreover, Kumar et al [ 10 ] prepared a Ag-coated PDMS SERS substrate using taro leaf as a template, achieving a very low MG detection limit of 10 −11 M, which could be attributed to the high local field produced by the Ag granular film and nanovoids on the PDMS surface.…”

Surface-enhanced Raman scattering (SERS) is a sensitive technique for the detection of low concentration analytes. In this study, we used cellulose fibers (CF) as the templates for the loading of silver nanoparticles (Ag NPs), and the obtained CF-Ag was applied in the detection of R6G and Malachite Green (MG) by surface-enhanced Raman scattering. The adsorption technique was employed in the sample preparation, and the optimal detecting status was identified in the dynamic range (sample status ranging from wet to dry) for different concentration of analytes. In comparison to Ag NPs, CF-Ag showed enhanced performance for adsorptive detection of Malachite Green, and the limit of detection was 5 × 10−12 M.

“…Moreover, it is used as a synthetic dye in various industries, such as paper, leather, textile, food and cosmetic industries, and is continuously entering the ecosystem from these industries . However, many reports have shown that MG is teratogenic, carcinogenic and mutagenic for both humans and animals . On the other hand, MG is relatively cheap, easy to obtain and highly effective.…”

“…As a result, monitoring fish and environmental samples to detect MG has become very important in recent decades. Thus far, several methods have been used to determine MG such as spectrophotometry after solid‐phase extraction or solid‐phase microextraction, spectrophotometry after cloud point extraction, high‐performance liquid chromatography (HPLC), electrochemistry and fluorescent probe . These methods have disadvantages such as being time consuming and laborious, as well as requiring sophisticated instruments.…”

BACKGROUND Malachite green is used in aquaculture and fisheries as a fungicide and antiseptic and it is also used in industry as a dye. However, malachite green is carcinogenic and highly toxic for humans and animals. In this study, a spectrophotometric method was developed to detect malachite green. The method was based on the surface plasmon resonance property of gold nanoparticles and interaction between malachite green and gold nanoparticles. RESULTS Malachite green–gold nanoparticles were rapidly aggregated in the acidic medium; as a result, a color change from red to blue was observed, which was easily detectable by the naked eye. The absorption ratio (A623/A520) of the gold nanoparticles in an optimized system exhibited a linear correlation with malachite green concentration. The method detection limit and linear range were 3 and 50–350 ng mL−1, respectively. The method was applied successfully to detect malachite green in different samples. CONCLUSION The method was simple and rapid to detect malachite green. The most important advantages of the method are the possibility of malachite green determination with very good accuracy and sensitivity using a simple UV–visible spectrometer without any expensive or sophisticated instrumentation and also the versatility of real samples. © 2018 Society of Chemical Industry
