“…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.…”

“…Yang et al [52] developed a magnetic mixed hemimicelles dSPE using an IL-coated ATP@polyaniline-polypyrrole@Fe 3 O 4 composite for the analysis of acaricides in fruit juice. The mechanism of the mixed hemimicelles dSPE involves the adsorption of ionic surfactants (ILs in this case) on metal oxides.…”

“…Thus, the use of dSPE procedures can overcome this disadvantage. In the mentioned application [52], the ATP@polyaniline-polypyrrole@Fe 3 O 4 was mixed with water and sonicated to form the magnetic fluid and added to the fruit juice. Then, 50 µL of 1-hexadecyl-3-methylimidazolium bromide was added and sonicated for 2 min to trap the analytes in the hemimicelles.…”

“…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.

BACKGROUND Carbadox and olaquindox have been banned from feeds since 1998 by the EU because of their mutagenic, photoallergic, and carcinogenic effects. Unfortunately, owing to their outstanding effect, they are frequently abused or misused in animal husbandry. There is an urgent need to develop a sensitive and reliable method for monitoring these drugs in animal feeds. RESULTS This work reported a new method of hydrophilic‐interaction‐based magnetically assisted matrix solid‐phase dispersion (MMSPD) extraction coupled with reversed‐phase liquid chromatography–mass spectrometry for simultaneous determination of carbadox and olaquindox in animal feeds. 3‐Trimethoxysilylpropyl methacrylate (γ‐MAPS)‐modified attapulgite (ATP) was crosslinked with γ‐MAPS‐modified iron(II,III) oxide (Fe3O4), 1‐vinyl‐3‐(butyl‐4‐sulfonate) imidazolium (VBSIm), acrylamide (AM), and N,N′‐methylene‐bis(acrylamide) (MBA) to synthesize ATP@Fe3O4@poly(VBSIm‐AM‐MBA) particles. The resultant particles were characterized by scanning electron microscopy, energy dispersive spectrometer, transmission electron microscopy, vibrating sample magnetometer, and Fourier transform infrared spectroscopy. Crosslinking of ATP into the magnetic particles has significantly increased the adsorption capacity of the particles. Under optimum conditions, the limits of detection (S/N = 3) were 0.3 μg kg−1 and 0.9 μg kg−1 for carbadox and olaquindox respectively. The intra‐day and inter‐day recoveries of the spiked targets in feed samples were in the range 83.5–98.3% with relative standard deviations of 1.0–8.3%. CONCLUSION With a simplified procedure and a low amount of sample, the proposed hydrophilic‐interaction‐based MMSPD method is not only useful for the determination of carbadox and olaquindox in feeds but also holds great promise for the analysis of other polar targets in solid or semisolid matrices. © 2021 Society of Chemical Industry.
