“…Veterinary drugs have played a positive role in reducing the morbidity and mortality of livestock and poultry, promoting growth, and improving product quality, and have been widely used in livestock production. At present, there are various veterinary drugs used in animal husbandry and production, including: chloramphenicol, [107] quinolones, [108] sulfonamides, [109] etc. Veterinary drugs are metabolized and absorbed by animals, accumulate in animals, and have direct toxic effects on humans.…”

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.

“…The crystal structure of Fe 3 O 4 MNPs was confirmed by the XRD pattern. As displayed in Figure 2A, five characteristic diffraction peaks respectively correspond to (220), (311), (400), (511), and (440) planes of the Fe 3 O 4 crystal [22], suggesting Fe 3 O 4 MNPs had been synthesized successfully. The chemical structure of the Fe 3 O 4 and Fe 3 O 4 /SiO 2 MNPs was characterized by FTIR spectroscopy (Figure 2B).…”

In this study, a hydroxyl‐rich ferrofluid was prepared by dispersing silica‐coated magnetic nanoparticles into a methyltrioctylammonium chloride‐glycerol deep eutectic solvent and then employed in the preconcentration of trace‐level of cinnamic acid derivatives (caffeic acid, p‐hydroxycinnamic acid, ferulic acid, and cinnamic acid) in traditional Chinese medicine prior to high‐performance liquid chromatography analysis. The structures of the synthesized materials were characterized by X‐ray diffraction and infrared spectroscopy. The experimental parameters affecting the extraction performance, such as deep eutectic solvent composition, dosage of ferrofluid, pH of aqueous sample solution, salt concentration, extraction time, type, and volume of desorption solvent, were studied and optimized. Under the optimum conditions, the enrichment factors of four cinnamic acid derivatives were in the range of 107–114. Low detection limits (0.2–0.9 ng/mL), good precisions (relative standard deviations 1.2%–9.5%), and satisfactory recoveries (96.0%–104.7%) were achieved. Subsequently, the possible microextraction mechanism of the proposed method was explored and elucidated. It showed that the prepared ferrofluid is easily dispersed in the aqueous sample and achieved recovery after the extraction. The developed approach is a simple, convenient, and efficient method for preconcentration and determination of cinnamic acid derivatives in complex matrices.

“…Nevertheless, the complicated matrix and extremely low concentration of QNs in food and water samples can influence detection results; therefore, an effective sample pretreatment is indispensable. Common sample pretreatment methods include liquid–liquid extraction(LLE), 13 dispersive liquid–liquid micro-extraction (DLLME), 14 solid phase extraction (SPE), 15–17 dispersive solid-phase extraction (DSPE) 18,19 and magnetic solid phase extraction (MSPE). 20–22 Different from conventional sample pretreatment methods, MSPE is a dispersed solid-phase extraction technique that uses magnetic materials as adsorbents to achieve the separation and enrichment of analytes by an external magnetic field.…”
