“…It should be noted that, in contrast, the polymers are relatively unstable at high temperatures (a problem which is exacerbated by the possible catalytic behaviour of the metallic core) [47]. Some selected examples of the application of the mentioned combination are shown in Table 3 [48][49][50][51][52][53][54][55][56][57].…”

“…Polymers are frequently combined with other materials (in addition to m-NPs) to improve extraction capacity, physical properties or to facilitate interaction. Thus, examples can be found in the literature of the combination with SiO 2 [49,53,54,56,57], carbonaceous materials [55,59], ionic liquids (ILs) [52] and quantum dots (QDs) [50]. It should be mentioned that, keeping in mind that the extraction mechanism involves different interactions when multi-material composites are used, some of the applications mentioned in this section could also be included in the preceding ones.…”

“…This way, a selective sorbent with superparamagnetism and good stability is obtained. Without any doubt, the great majority of applications of m-NPs combined with polymers for the analysis of foods have used a MIP [48,50,53].…”

“…Finally, it should be mentioned that although m-dSPE was the most common extraction technique, this kind of particle was also adequate for other methodologies [52,53]. In this regard, Li et al [53] developed a stir bar coated with Fe 3 O 4 @SiO 2 @MIP NPs for the extraction of clonazepam and norazepan from herbal health food matrices (recovery values: 89.8-103.3%, LOD: 0.01 µg/mL) and Yang et al [52], as it was previously mentioned, employed a 1-hexadecyl-3-methylimidazolium bromide -coated ATP@polyaniline-polypyrrole@Fe 3 O 4 composite in m-mixed hemimicelles SPE.…”

Nanotechnology has become a topic of interest due to the outstanding advantages that the use of nanomaterials offers in many fields. Among them, magnetic nanoparticles (m-NPs) have been one of the most widely applied in recent years. In addition to the unique features of nanomaterials in general, which exclusively appear at nanoscale, these present magnetic or paramagnetic properties that result of great interest in many applications. In particular, in the area of food analysis the use of these nanomaterials has undergone a considerable increase since they can be easily separated from the matrix in sorbent-based extractions, providing a considerable simplification of the procedures. This allows reducing cost and giving fast responses, which is essential in the food trade to guarantee consumer safety. These materials can also be easily tunable, providing higher selectivity. Moreover, their particular electrical, thermal and optical characteristics allow enhancing sensor signals, increasing the sensitivity of the approaches based on this type of device. The aim of this review article is to summarise the most remarkable applications of m-NPs in food analysis in the last five years (2016–2020) showing a general view of the use of such materials in the field.

“…The selectivity of SBA-15@MT-MIPs is closely related to the number and shape of binding sites 243 within the polymer network structure, as well as the rigidity of the complexes formed by template 244 molecule and functional monomer [36]. Therefore, monomer selection is the first priority for the 245 synthesis of SBA-15@MT-MIPs with good affinity and high selectivity.…”
