“…used lab synthesized Pts @ MNPs for MSPE of pyrethroids residue in fruit peels and fleshes prior to HPLC analysis. The results exhibited that the proposed method in this research could be used to extract pyrethroids residues from complex samples with low LOD, LOQ, RSD, and high recoveries (Yu, Li, Ng, Yang, & Wang, 2018). The same Pts @ MNPs composites have also been used to extract pyrethroid residues from vegetables.…”

Pesticide residues in food matrices, threatening the survival and development of humanity, is one of the critical challenges worldwide. Metal–organic frameworks (MOFs) possess excellent properties, which include excellent adsorption capacity, tailorable shape and size, hierarchical structure, numerous surface‐active sites, high specific surface areas, high chemical stabilities, and ease of modification and functionalization. These promising properties render MOFs as advantageous porous materials for the extraction and detection of pesticides in food samples. This review is based on a brief introduction of MOFs and highlights recent advances in pesticide extraction and detection through MOFs. Furthermore, the challenges and prospects in this field are also described.

“…Subsequently, analytes were desorbed from the sorbent with methanol. Compared with the magnetic liquid-solid extraction (MLSE) [ 58 , 59 ], a hot topic of nanomaterials in sample preparation, the major difference between MA-MSPD and MLSE is the manipulation of sample. For MLSE, analytes in solid sample are extracted into the liquid solution prior to the introduction of magnetic sorbent.…”

Matrix solid phase dispersion (MSPD) has proven to be an efficient sample preparation method for solid, semi-solid, and viscous samples. Applications of MSPD have covered biological, food, and environmental samples, including both organic and inorganic analytes. This review presents an update on the development of MSPD in the period 2015~June 2018. In the first part of this review, we focus on the latest development in MSPD sorbent, including molecularly imprinted polymers, and carbon-based nanomaterials etc. The second part presents the miniaturization of MSPD, discussing the progress in both micro-MSPD and mini-MSPD. The on-line/in-line techniques for improving the automation and sample throughput are also discussed. The final part summarizes the success in the modification of original MSPD procedures.

“…Yu et al compared the pyrethroid residues (bifenthrin, cypermethrin, decamethrin, fenvalerate, fenpropathrin, and Permethrin) in fruit peels and flesh. He synthesized polystyrene-coated nanoparticles, and performed an MSPE procedure for determination [7]. Suthasinee Boonchiangma et al determined six pyrethroid residues in various fruit juices by applying dispersive liquid-liquid microextraction (DLLME) coupled to high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection [8].…”

Pyrethroid residues in traditional Chinese medicines have been a serious threat to the health and treatment of patients. However, because of the matrix complexity of traditional Chinese medicine, the detection of pyrethroid residues remains a challenge. Therefore, we developed a QuEChERS method coupled with high-performance liquid chromatography and ultraviolet detection (HPLC-UV) for the determination of pyrethroid pesticides in three kinds of traditional Chinese medicine oral liquid preparations, and we investigated and optimized the extraction conditions. The matrix effect was estimated in the organic solvent and the actual samples by comparing the slopes of calibration curves, and the results showed that the matrix effect is not significant when using the modified QuEChERS method. The pyrethroid pesticides could be completely separated in 30 min. The linear correlation coefficients were more than 0.999, and the recoveries of all the pyrethroid pesticides ranged from 87.2% to 104.8%. The intra-day precisions (n = 5) were 2.44–4.62%, and the inter-day precisions (n = 5) were 1.06–3.02%. Moreover, the limits of detection were in the range of 0.007–0.018 ng mL-1, while the limits of quantitation were in the range of 0.022–0.057 ng mL-1. This simple, low-cost, and highly sensitive analytical method can be a potential tool for the analysis of pyrethroid residues in traditional Chinese medicine oral liquid preparations.
