“…An alternative to sol-gel is the synthesis of monoliths by polymerization. The general procedure implies filling a template with a pre-polymeric solution (containing the MOF powder dispersed or its precursors), polymerization, removal of the template, and a final wash to clean the monolith [76,140,141]. Thus, the shape and dimension of the devices depends on the template and not on the support.…”

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.

“…The main difference between SPME and SBSE is that SBSE uses an extraction phase about 50–250 times larger than SPME, resulting in higher absolute recoveries and higher sample capacity (He, Chen, & Hu, ). SBSE has found applications in environmental analysis (He et al, ), food analysis (Ayazi & Jaafarzadeh, ; Yao et al, ; You, He, Chen, & Hu, ) and bioanalysis (Manandhar, Maslamani, Petrikovics, Rockwood, & Logue, ). General review articles about SBSE are available (He et al, ; Nogueira, ).…”

Sample preparation is a critical step in forensic analytical toxicology. Different extraction techniques are employed with the goals of removing interferences from the biological samples, such as blood, tissues and hair, reducing matrix effects and concentrating the target analytes, among others. With the objective of developing faster and more ecological procedures, microextraction techniques have been expanding their applications in the recent years. This article reviews various microextraction methods, which include solid-based microextraction, such as solidphase microextraction, microextraction by packed sorbent and stir-bar sorptive extraction, and liquid-based microextraction, such as single drop/hollow fiber-based liquid-phase microextraction and dispersive liquid-liquid microextraction, as well as their applications to forensic toxicology analysis. The development trend in future microextraction sample preparation is discussed.

“…MOF/polymer monoliths can be adapted to less conventional formats for sample preparation. As an example, a monolithic coating based on the ZIF‐8 (Zn(II)‐2‐methylimidazole) and a methyl methacrylate‐based poly(MMA‐ co ‐EDMA) polymer monolith was in situ synthesized on a stir bar by one‐pot polymerization . The developed support for stir bar sorptive extraction (SBSE) is an alternative format to MOF/polymer columns, especially useful for the sample pretreatment of complex sample matrices, as demonstrated for the extraction of phytohormones from fruit samples.…”

Dedicated to Professor Frantisek Svec on the occasion of his 75th BirthdayThis review summarizes recent developments made in the incorporation of functional materials into organic polymer monoliths, together with new monolithic forms and formats, which enhance their application as supports and stationary phase materials for sample preparation and chromatographic separations. While polymer monoliths are well-known supports for the separation of large molecules, recent developments have been made to improve their features for the separation of small molecules. The selectivity and performance of organic polymer monoliths has been improved by the incorporation of different materials, such as metal-organic frameworks, covalent organic frameworks, or other types of nanostructured materials (carbon nanohorns, nanodiamonds, polyoxometalates, layered double hydroxides, or attapulgite). The surface area of polymer monoliths has been significantly increased by polymer hypercrosslinking, resulting in increased efficiency when applied to the separation of small molecules. In addition, recent exploration of less conventional supports for casting polymer monoliths, including photonic fibres and 3D printed materials, has opened new avenues for the applications of polymer monoliths in the field of separation science. Recent developments made in these topics are covered, focusing on the strategies followed by the authors to prepare the polymer monoliths and the effect of these modifications on the developed analytical applications.
