“…In this regard, the development of very sensitive, rapid and selective methodologies results essential and the use of nanomaterials is a cornerstone to achieve these goals [4]. In recent years, nanotechnology has played an important role in many areas, including food analysis as it has been shown in many reports in the literature [1,[4][5][6][7]. Particular attention has been paid to the use of nanoparticles (NPs) and, especially, in magnetic-NPs (m-NPs) [1,8].…”

“…In fact, to the best of our knowledge, modified m-NPs have been used in all works published in the last five years in sample preparation, and the use of non-modified m-NPs only has been reported for the preparation of sensors used for the evaluation of inorganic compounds [16]. Besides, such combinations aso allow increasing their selectivity of the sorbents and the number of active points on the surface or enhancing electrical and optical properties in sensors [1,4,5]. In this respect, they have been combined with polymers or specific molecularly imprinted polymers (MIPs), with different types of aptamers (Apts) and antibodies (Abs), especially in sensor applications, or even with one or more nanomaterials including metal-organic frameworks (MOFs), carbon based nanomaterials and other types of NPs.…”

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.

“…MOFs have some unique properties, such as permanent nanoscale porosity, high surface area, costly diversity in their structures, tunable pore size, structure flexibility, and high loading capacity [18]. These compounds have been employed in various research fields, especially in separation science, gas storage, catalysis, sensor technology, drug delivery, and biomedical imaging [19]. In comparison with typical adsorbents like polyacrylate (PA), polydimethylsiloxane (PDMS), activated carbon, and zeolites (with a surface area of about 150, 450, 1500 and 300 m 2 ·g −1 , respectively), MOFs have much larger surface areas, even up to 7000 m 2 ·g −1 [20].…”

The performance of headspace solid-phase microextraction (HS-SPME) was upgraded by easy and low-cost preparation of a new nanocomposite fiber. A polypyrrole/chromium-based metal–organic framework, PPy@MIL-101(Cr), nanocomposite was electrochemically synthesized and simultaneously coated on a steel wire as a microextraction sorbent. The morphology and chemical structure of the prepared nanocomposite was characterized by Fourier-transform infrared spectrometry (FT-IR), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX) techniques. The microsorbent was used for sampling of methyl-tert-butyl ether (MTBE) in solid samples, through an HS-SPME sampling strategy, followed by GC-FID measurement. The optimal experimental conditions, including extraction temperature, extraction time, and GC desorption conditions, were evaluated and optimized. The proposed procedure showed good sensitivity (limit of detection was 0.01 ng·g−1) and precision (relative standard deviation was 8.4% for six replicated analyses). The calibration curve was linear over the range of 5–40,000 ng·g−1, with a correlation coefficient of 0.994. The limit of quantification was 0.4 ng·g−1. The fabricated fiber exhibited good repeatability and reproducibility for the sampling of MTBE, with average recovery values of 88–114%. The intra-fiber and inter-fiber precisions were found to be 8.4% and 19%, respectively. The results demonstrated the superiority of the PPy@MIL-101(Cr)-coated fiber in comparison with handmade (polypyrrole, PPY) and commercial fibers (polyacrylate, PA; polydimethylsiloxane, PDMS; and divinylbenzene/carboxen/polydimethylsiloxane, DVB/CAR/PDMS) for the analysis of solid samples. The developed method was successfully employed for the analysis of MTBE in different soil samples contaminated by oil products.

“…Recently, particles of Fe 3 O 4 ‐coated polypyrrole (Zhao et al., 2016) and graphene oxide (Santana‐Mayor et al., 2018) have been used to preconcentrate and determine phthalate esters in water samples. Graphene oxide has attracted interest as a promising sorbent material due to its hydrophilicity, ultrahigh surface area, and high dispersion stability (González‐Sálamo, Socas‐Rodríguez, Hernandez‐Borges, & Rodríguez‐Delgado, 2016). In this regard, several PAEs also have been determined using graphene oxide (Wang, Song, & Deng, 2015; Wu et al., 2013; Ye, Liu, & Chen, 2014); however, nanoscale materials possess some disadvantages in terms of their large‐scale synthesis and hazards associated with their postadsorption disposal (Shaida, Dutta, & Sen, 2018).…”

Newly developed magnetic carbon particles prepared from coffee grounds were used as the sorbent for the magnetic solid-phase extraction of eight phthalic acid esters (PAEs) from plastic bottled water prior to their analysis by GC-MS. The method, which uses coffee-ground particles coated with iron oxide, was validated, and exhibited linearities for the eight PAEs, with coefficients of determination above 0.998 in the 0.005 to 0.1 mg/L concentration range. Limits of detection and limits of quantification of 0.00003 to 0.002 mg/L and 0.0001 to 0.005 mg/L, respectively, were achieved, with recoveries (%) ranging between 77% and 120%, and relative standard deviations for intra-and interday precisions below 16.3% at three fortification levels. No PAE residues were detected when the developed and validated method was applied to 10 real plastic bottled water samples. Taken together, the developed magnetic solid-phase extraction method is a useful tool for monitoring phthalate esters in aqueous samples.Practical Application: The development of a new, inexpensive, and efficient magnetic sorption material derived from spent coffee grounds, and its ability to determine phthalate esters in aqueous solutions was described by GC-MS/MS. The developed magnetic solid-phase extraction method is a useful tool for monitoring phthalate esters in aqueous samples.
