“…Generally, the fundamental principle governing most extraction procedures is the equilibrium partition of target analytes between the sample and the extraction phase coated on the surface of magnetic nanoparticles. Hence, the adsorbent coating assumes a pivotal role in the magnetic solid-phase extraction (MSPE) process, given its structural 22 and inherent properties that substantially influence extraction capacity and selectivity. Consequently, developing novel materials that can function as stable and effective coatings for MSPE sorbents becomes imperative.…”

“…At present, the detection technology of food contaminants has matured, but in practical applications, the detection of food contaminants relies on cumbersome instruments, such as gas chromatography (GC), high-performance liquid chromatography (HPLC), gas chromatography–mass spectrometry (GC-MS), − liquid chromatography–mass spectrometry (LCMS), enzyme-linked immunosorbent assay (ELISA), etc. − They can achieve high detection accuracy and stability, but they cannot achieve rapid on-site or nondestructive testing of food contaminants due to limitations such as heavy instrumentation, chemical pretreatment, and complex operations. − It is of great significance to use the method of on-site rapid inspection of food contaminants to carry out a large number of screenings, find suspicious problems in time, and quickly take corresponding measures, to improve the efficiency of supervision and ensure food safety. − Therefore, a real-time, sensitive, and rapid detection technology is required for food contaminants to minimize the risk of food contaminants endangering food safety.…”

Food quality and safety are related to the health and safety of people, and food hazards are important influencing factors affecting food safety. It is strongly necessary to develop food safety rapid detection technology to ensure food safety. As a new detection technology, artificial nanochannel-based electrochemical and other methods have the advantages of being real-time, simple, and sensitive and are widely used in the detection of food hazards. In this paper, we review artificial nanochannel sensors as a new detection technology in food safety for different types of food hazards: biological hazards (bacteria, toxins, viruses) and chemical hazards (heavy metals, organic pollutants, food additives). At the same time, we critically discuss the advantages and disadvantages of artificial nanochannel sensor detection, as well as the restrictions and solutions of detection, and finally look forward to the challenges and development prospects of food safety detection technology based on the limitations of artificial nanochannel detection. We expect to provide a theoretical basis and inspiration for the development of rapid real-time detection technology for food hazards and the production of portable detection equipment in the future.

“…Metal-organic frameworks (MOFs) have attracted much attention due to their large specific surface area, ultra-high porosity, and tunable pore size. However, the selectivity of the ferrous MOFs is poor, and they are unable to remove low concentrations of pollutants with specificity [24][25][26][27][28][29][30][31]. Molecularly imprinted polymers (MIPs) have been widely used to separate and enrich PAEs, as they possess specific recognition sites that are complementary to the size and shape of the template molecules [32][33][34][35][36][37].…”

In this study, a novel magnetic molecularly imprinted polymeric material (Fe3O4@MOF@MIP-160) with a metal-organic backbone (Fe3O4@MOF) carrier was prepared using dibutyl phthalate (DBP) as a template. The material can be used for the efficient, rapid, and selective extraction of trace amounts of phthalic acid esters (PAEs) in food and can detect them via gas chromatography-mass spectrometry (GC-MS). The synthesis conditions of the materials were optimized to prepare the Fe3O4@MOF@MIP160 with the highest adsorption performance. Transmission electron microscopy (TEM), Fourier Transform Infrared Spectra (FT-IR), Vibration Sample Magnetic (VSM), and the Brunauer–Emmett–Teller (BET) method were used to characterize the materials. Compared with Fe3O4@MOF and the magnetic non-imprinted polymeric material (Fe3O4@MOF@NIP), Fe3O4@MOF@MIP-160 possesses the advantages of easy and rapid manipulation of magnetic materials, the advantages of high specific surface area and the stability of metal–organic frameworks, and the advantages of high selectivity of molecularly imprinted polymers. Fe3O4@MOF@MIP-160 has good recognition and adsorption capacity for di-butyl phthalate (DBP) and diethylhexyl phthalate (DEHP): the adsorption capacity for DBP and DEHP is 260 mg·g−1 and 240.2 mg·g−1, and the adsorption rate is fast (reaching equilibrium in about 20 min). Additionally, Fe3O4@MOF@MIP160 could be recycled six times, making it cost-effective, easy to operate, and time-saving as compared to traditional solid-phase extraction materials. The phthalate ester content in drinking water, fruit juice, and white wine was analyzed, with recoveries ranging from 70.3% to 100.7%. This proved that Fe3O4@MOF@MIP160 was suitable for detecting and removing PAEs from food matrices.
