The residues of sulfonamides (SAs) may transfer to the human body through the food chain, causing risks to human health. Therefore, it is of significance to address the SA residues in food products. Recently, the development of nanomaterial adsorbents with fast adsorption, low toxicity, robustness, and reusability has attracted much attention. CiteSpace software was used in this work to analyze studies on the detection of SAs in the past five years. Furthermore, novel nanomaterials, including magnetic nanomaterials, metal_organic framework materials (MOFs), and covalent organic framework materials (COFs), are reviewed in detail for extraction and analysis of SAs in food, showing the advantages in the adsorption and analysis performance of these nanomaterials. Challenges and prospects of related research are also discussed to clarify the future directions for the achievement of food safety. This review is expected to provide new insights for the development of efficient adsorbents and analytical methods for food pollutants with potential applications.

“…28,29 The three-dimensional network structure of nanofiber membrane facilitates the transfer and diffusion of particles within membrane, which efficiently reduces the capture time. 30 Furthermore, combining electrospun nanofibers with other nanomaterials or introducing functional groups on nanofibers through chemical modification can not only introduce more active sites into the nanofiber adsorbents, further enhancing the adsorption capacity and selectivity of nanofiber membranes, 31 but also avoid the problem of segregating samples from nanoscale adsorbents after magnetic adsorbents extraction. 32,33 Notably, Au and Ag nanoclusters have been widely studied in the field of OTs analysis, while copper (Cu) nanoclusters with similar properties have hardly been explored.…”

“…Compared with other solid-phase adsorbents such as nanoparticles and nanotubes, which may create a adsorbents leaking or aggregation of nanoparticles in the SPE column during the extraction process, the mats and cotton like bundles of nanofibers have better chemical and mechanical stability, and it is easier filled into the column. , The three-dimensional network structure of nanofiber membrane facilitates the transfer and diffusion of particles within membrane, which efficiently reduces the capture time . Furthermore, combining electrospun nanofibers with other nanomaterials or introducing functional groups on nanofibers through chemical modification can not only introduce more active sites into the nanofiber adsorbents, further enhancing the adsorption capacity and selectivity of nanofiber membranes, but also avoid the problem of segregating samples from nanoscale adsorbents after magnetic adsorbents extraction. , Notably, Au and Ag nanoclusters have been widely studied in the field of OTs analysis, while copper (Cu) nanoclusters with similar properties have hardly been explored. , Therefore, introducing copper nanoparticles into electrospinning nanofibers for OTs adsorption is a method worth trying.

In this study, several electrospun nanofibers were prepared and characterized, and the electrospun polystyrene/ poly(ether sulfone) nanofiber coated with copper nanoparticles (PS/PES-CuNP nanofibers) was selected and utilized as solidphase extraction adsorbent. And then, the packed-fiber solid-phase extraction coupled with high-performance liquid chromatographyfluorescence detection method was established for the efficient determination of ochratoxins in foods. With the proposed method, several factors including the type and dosage of nanofibers, sample pH, extraction time, type, and volume of elution solvent were optimized. The results suggested that low limit of detection (0.102−0.126 ng/mL), limit of quantification (0.382−0.436 ng/ mL), and recoveries (85.5−111.1%) for ochratoxin A, B, and C with relative standard deviations <7% were achieved. As-synthesized PS/PES-CuNP nanofibers displayed satisfactory potential practical application in the simultaneous pretreatment and determination of mycotoxins in complex matrice samples.

“…Tian et al fabricated electrospun covalent organic framework/polyacrylonitrile nanofiber as an adsorbent for the determination of plant growth regulators [ 38 ]. In our previous work, PAN/Tp-BD nanofiber was also used as an adsorbent to extract seven sulfonamides from the food matrix [ 39 ]. We fabricated superhydrophobic PAN/Tp-BD and PAN/TAPB-TPA nanofiber membranes at room temperature and applied them to separate water-in-oil mixtures [ 40 ].…”

The extraction of quinolone antibiotics (QAs) is crucial for the environment and human health. In this work, polyacrylonitrile (PAN)/covalent organic framework TpPa–1 nanofiber was prepared by an electrospinning technique and used as an adsorbent for dispersive solid-phase extraction (dSPE) of five QAs in the honey and pork. The morphology and structure of the adsorbent were characterized, and the extraction and desorption conditions for the targeted analytes were optimized. Under the optimal conditions, a sensitive method was developed by using PAN/TpPa–1 nanofiber as an adsorbent coupled with high-performance liquid chromatography (HPLC) for five QAs detection. It offered good linearity in the ranges of 0.5–200 ng·mL−1 for pefloxacin, enrofloxacin, and orbifloxacin, and of 1–200 ng·mL−1 for norfloxacin and sarafloxacin with correlation coefficients above 0.9946. The limits of detection (S/N = 3) of five QAs ranged from 0.03 to 0.133 ng·mL−1. The intra-day and inter-day relative standard deviations of the five QAs with the spiked concentration of 50 ng·mL−1 were 2.8–4.0 and 3.0–8.8, respectively. The recoveries of five QAs in the honey and pork samples were 81.6–119.7%, which proved that the proposed method has great potential for the efficient extraction and determination of QAs in complex samples.
