“…Magnetic haemocompatible adsorbents were also proposed for extracorporeal detoxification of blood [ 76 ]. A schematic illustration of the magnetic solid phase extraction (MSPE) is reported in Figure 5 [ 77 ]. First, the magnetic adsorbent is added to the solution containing the substance to be removed.…”

“…This is clearly shown in Figure 5 . On the contrary, the ex-situ approach revealed in some cases agglomeration phenomena of Fe 3 O 4 nanoparticles on the surface of the resin beads [ 77 ]. For what concerns the large-scale applicability of these systems, even if some results were reported on their reusability and fouling resistance [ 80 ], their long-term efficiency still needs a deeper evaluation.…”

Abstract:Hyper-crosslinked (HCL) polystyrenes show outstanding properties, such as high specific surface area and adsorption capability. Several researches have been recently focused on tailoring their performance for specific applications, such as gas adsorption and separation, energy storage, air and water purification processes, and catalysis. In this review, main strategies for the realization of HCL polystyrene-based materials with advanced properties are reported, including a summary of the synthetic routes that are adopted for their realization and the chemical modification approaches that are used to impart them specific functionalities. Moreover, the most up to date results on the synthesis of HCL polystyrene-based nanocomposites that are realized by embedding these high surface area polymers with metal, metal oxide, and carbon-based nanofillers are discussed in detail, underlining the high potential applicability of these systems in different fields.

Functionalized Inorganic Nanoparticles for Magnetic Separation and SERS Detection of Water Pollutants

et al. 2018

Inorganic nanoparticles (NPs) have emerged in the last decades as key materials for a number of technologies. In particular, noble metal (Ag, Au) and iron oxide NPs have revealed important applications due to their plasmonic and magnetic properties, respectively. Among these applications, this review provides, on one hand, an overview on the use of colloidal metal NPs in surface enhanced Raman scattering (SERS) chemical analysis and, on the other hand, the application of iron oxides as a new class of nanosorbents for water pollutants. These distinct types of NPs are the main building blocks to produce [a] Raman spectroscopy is a powerful analytical tool for chemical characterization, providing information about molecular structure, surface processes, and interface reactions. [31,32] Raman spectroscopy is based on the inelastic scattering of photons by chemical species and materials (Raman scattering). Among the incident photons that hit the sample only a small portion is inelastically scattered, i.e. comes out at a different frequency from the incident light. The spectral information is based on the detection of these scattered photons that are recorded as energy shifts (Raman shifts) from the wavenumber of the elastic scattered photons (Rayleigh scattering). Each band in the Raman spectrum can be assigned to a vibrational mode (or Paula

“…Apart from that, m-NPs are characterised by other particular features such as high electrical conductivity, coercivity, high magnetic susceptibility and, especially, superparamagnetism that favour their separation from the samples, simplifying the procedures, shortening times and, consequently, reducing costs [1,9]. These characteristics make them ideal for the preparation of sorbents in microextraction techniques or for clean-up steps [8,10,11] and as materials for the preparation of sensors [1,10,12]. In this respect, their use in magnetic-micro-dispersive solid-phase extraction (m-µ-dSPE) has constituted their main application, while their utilisation in optical and electrochemical sensors has involved the main uses in these approaches, although other novel systems have also been described in the literature.…”

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.
