“…The introduction of MOFs as sorbent materials in the different SPME devices and configurations has been gradual. Thus, Figure 3 shows a timeline of the introduction of MOFs in the main different SPME configurations developed up to date [47][48][49][50][51][52].…”

“…Even the use a support is not required if magnetic nanoparticles are dispersed in the pre-polymeric suspension [76]. Recently, Du et al took advantage of this strategy for the preparation of the first MOF-based sc-SPME device by dispersing Fe 3 O 4 @HKUST-1 core-shell particles in a pre-polymeric solution of 2-ethylhexylacrylate/divinylbenzene/methyl methacrylate [52]. Although the MOF composite monolith does not utilize a classical sc-SPME support, its visual geometry and shape resembles that of the classical sc-SPME device.…”

Metal–Organic Frameworks as Key Materials for Solid-Phase Microextraction Devices—A Review

et al. 2019

View full text Add to dashboard Cite

Metal–organic frameworks (MOFs) have attracted recently considerable attention in analytical sample preparation, particularly when used as novel sorbent materials in solid-phase microextraction (SPME). MOFs are highly ordered porous crystalline structures, full of cavities. They are formed by inorganic centers (metal ion atoms or metal clusters) and organic linkers connected by covalent coordination bonds. Depending on the ratio of such precursors and the synthetic conditions, the characteristics of the resulting MOF vary significantly, thus drifting into a countless number of interesting materials with unique properties. Among astonishing features of MOFs, their high chemical and thermal stability, easy tuneability, simple synthesis, and impressive surface area (which is the highest known), are the most attractive characteristics that makes them outstanding materials in SPME. This review offers an overview on the current state of the use of MOFs in different SPME configurations, in all cases covering extraction devices coated with (or incorporating) MOFs, with particular emphases in their preparation.

“…Their combination with m-NPs to form the so-called magnetic MOFs (m-MOFs) or magnetic frameworks composites (m-FCs) provides them in general with a better stability than MOFs alone, as well as superparamagnetism, rapid and easy adsorption/desorption steps and high recycling rates. Table 2 shows a selection of recent applications of m-MOFs to the food analysis field [33][34][35][36][37][38][39][40][41][42]. The works reported describe the extraction of both organic [33,34,[36][37][38][41][42][43] and inorganic [39,40] compounds in a wide variety of matrices.…”

“…a LOD of 5.0 ng/L and recovery values between 87-96%. Apart from the aforementioned works, there are others in the literature which combine the use of m-MOFs with other systems to improve the extraction of the analytes [41,42]. This is the case of the work developed by Senosy et al [41] in which ZIF-8 modified magnetic GO was employed to extract a group of triazole fungicides in honey and fruit juices.…”

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.

Emulsion templating is at the forefront of producing a wide array of porous materials that offers interconnected porous structure, easy permeability, homogeneous flow-through, high diffusion rates, convective mass transfer, and direct accessibility to interact with atoms/ions/molecules throughout the exterior and interior of the bulk. These interesting features together with easily available ingredients, facile preparation methods, flexible pore-size tuning protocols, controlled surface modification strategies, good physicochemical and dimensional stability, lightweight, convenient processing and subsequent recovery, superior pollutants remediation/monitoring performance, and decent recyclability underscore the benchmark potential of the emulsion-templated porous materials in large-scale practical environmental applications. To this end, many research breakthroughs in emulsion templating technique witnessed by the recent achievements have been widely unfolded and currently being extensively explored to address many of the environmental challenges. Taking into account the burgeoning progress of the emulsion-templated porous materials in the environmental field, this review article provides a conceptual overview of emulsions and emulsion templating technique, sums up the general procedures to design and fabricate many state-of-the-art emulsion-templated porous materials, and presents a critical overview of their marked momentum in adsorption, separation, disinfection, catalysis/degradation, capture, and sensing of the inorganic, organic and biological contaminants in water and air.
