“…Chauhan et al [ 61 ] used precipitation polymerisation with MAA as the functional monomer and produced an average particle size of 300 nm. Abdulhussein et al [ 62 ] also synthesised MT-MIP using precipitation polymerisation. They used 2-VP and obtained particles >50 nm.…”

“…The use of initiators is very important because the success of free radical polymerisation depends on this molecule. The initiator commonly used is azobis, and other initiators include AIBN, 1,1′-azobis-(cyclohexanecarbonitrile) (AHCN), 2,2′-azobis (2,4-dimethyl valeronitrile) (AMVN), and 4,4′-azobis (4-cyanovaleric acid) (ACV) [ 32 , 54 , 62 , 75 , 117 ].…”

A multi-template molecularly imprinting polymer (MT-MIP) strategy has been proposed and is increasingly utilised to synthesise MIP with multiple recognition sites in a single polymer using multiple target species as templates. This approach can expand MIP applications for simultaneous recognition and extraction of more than one analyte. The advantages of MT-MIP are simultaneous analyte extraction in one process, lower solvent consumption, cost-effectiveness, and short analysis time. The use of multiple templates to prepare a MIP reduces the effort required to prepare different MIPs for different analytes separately. Although there are many studies about developing MT-MIP, there are no review articles that discuss the success rate of MT-MIP. Therefore, in this review, we summarise MT-MIP synthesis, including the polymerisation method being used, the important factors that affect the quality of MT-MIP, and MT-MIP applications. MT-MIP has great potential in chemical isolation and analysis. MT-MIP produces a product that has good sensitivity, selectivity, and reusability. Furthermore, many templates, functional monomers, and crosslinkers can be formulated as MT-MIP and have a high success rate. This is evidenced by the good values of the maximum absorption capacity (Qmax), imprinting factor (IF), and reusability. We expect that the evidence presented in this review can encourage additional research on the development and application of MT-MIP.

“…For example, Xu et al [ 19 ] modified MNM with carbon nanotubes for extracting pollutants in egg. The modification of MNM with molecularly imprinted polymer for the analysis of thiamethoxam and thiacloprid in honey was also reported [ 98 ]. Other limitations of MNMs are that bare MNM can easily be oxidized and form hydrated oxides in acidic atmospheres or, when exposed to air [ 92 ], the thermally unstable and stationary phase components of the MNM can completely or partly degrade during the desorption process at high temperature, which leads to reduction in precision and accuracy of the analysis.…”

Environmental pollutants, such as mycotoxins, pesticides, and pharmaceuticals, are a group of contaminates that occur naturally, while others are produced from anthropogenic sources. With increased research on the adverse ecological and human health effects of these pollutants, there is an increasing need to regularly monitor their levels in food and the environment in order to ensure food safety and public health. The application of magnetic nanomaterials in the analyses of these pollutants could be promising and offers numerous advantages relative to conventional techniques. Due to their ability for the selective adsorption, and ease of separation as a result of magnetic susceptibility, surface modification, stability, cost-effectiveness, availability, and biodegradability, these unique magnetic nanomaterials exhibit great achievement in the improvement of the extraction of different analytes in food. On the other hand, conventional methods involve longer extraction procedures and utilize large quantities of environmentally unfriendly organic solvents. This review centers its attention on current applications of magnetic nanomaterials and their modifications in the extraction of pollutants in food commodities.
