“…These novel miniaturized approaches require outstanding materials to perform with the same analytical performance as conventional materials in non-miniaturized methods. Among miniaturized sorbent-based microextraction strategies incorporating MOFs it is possible to cite: miniaturized solid-phase extraction (µ-SPE) [30], dispersive solid-phase microextraction (µ-dSPE) and its magnetic-assisted version (m-µ-dSPE) [25,31], and solid-phase microextraction (SPME) [24,32], each of which are also susceptible to be performed under different operational strategies, as shown in Figure 2.…”

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.

“…Despite the sophisticated and highly sensitive techniques that have been developing in the analytical field in the last few decades, the determination of analytes in complex samples such as environmental, food, or biological matrices requires previous and efficient pretreatment steps in order to make analytes suitable for their introduction in the analytical system. Within sample preparation techniques, solid-phase extraction (SPE) is the most common technique used for isolation and enrichment purposes [ 16 , 17 , 18 , 19 , 20 ]. In this sense, the abovementioned bio-MOFs and their features [ 21 ] can be a good alternative to commercial SPE sorbents in order to provide high extraction efficiencies, a good clean-up in short analysis times, and a low cost.…”

This review summarizes the recent advances concerning metal–organic frameworks (MOFs) modified with several biomolecules (e.g., amino acids, nucleobases, proteins, antibodies, aptamers, etc.) as ligands to prepare affinity-based sorbents for application in the sample preparation field. The preparation and incorporation strategies of these MOF-based affinity materials were described. Additionally, the different types of ligands that can be employed for the synthesis of these biocomposites and their application as sorbents for the selective extraction of molecules and clean-up of complex real samples is reported. The most important features of the developed biocomposites will be discussed throughout the text in different sections, and several examples will be also commented on in detail.

“…However accurate and quick a method should be, samples arriving at the laboratory can rarely be analyzed without any preparation. Environmental samples often exhibit complex matrixes containing many particulate and chemical interferents, rendering them unsuitable for immediate analysis [ 1 , 2 , 3 ]. Nearly every sample needs to be subjected to treatment aimed at separating the analyte from the matrix, allowing for reliable analysis.…”

“…Nearly every sample needs to be subjected to treatment aimed at separating the analyte from the matrix, allowing for reliable analysis. For more complex samples, this can necessitate the employment of multiple complicated procedures, in which case the sample pre-treatment becomes the bottleneck of the entire analytical process [ 1 , 2 , 4 ]. As measurement becomes faster and more accurate, the drive to develop effective, simple, selective, rapid, reliable and green clean-up and pre-concentration techniques is as strong as ever.…”

Solid phase extraction (SPE) is an analytical procedure developed with the purpose of separating a target analyte from a complex sample matrix prior to quantitative or qualitative determination. The purpose of such treatment is twofold: elimination of matrix constituents that could interfere with the detection process or even damage analytical equipment as well as enriching the analyte in the sample so that it is readily available for detection. Dispersive solid phase extraction (dSPE) is a recent development of the standard SPE technique that is attracting growing attention due to its remarkable simplicity, short extraction time and low requirement for solvent expenditure, accompanied by high effectiveness and wide applicability. This review aims to thoroughly survey recently conducted analytical studies focusing on methods utilizing novel, interesting nanomaterials as dSPE sorbents, as well as known materials that have been only recently successfully applied in dSPE techniques, and evaluate their performance and suitability based on comparison with previously reported analytical procedures.
