“…The separation field is continuously expanding driven by the needs of the pharmaceutical and chemical industries, and by the demands for water purification and waste remediation. By virtue of their high affinity and selectivity, MIPs have been employed as stationary phases in high performance liquid chromatography [120], capillary chromatography [121,122], and solid phase extraction [123]. The nano format however is not ideally suited for large-scale separation.…”

Materials that can mimic the molecular recognition-based functions found in biology are a significant goal for science and technology. Molecular imprinting is a technology that addresses this challenge by providing polymeric materials with antibody-like recognition characteristics. Recently, significant progress has been achieved in solving many of the practical problems traditionally associated with molecularly imprinted polymers (MIPs), such as difficulties with imprinting of proteins, poor compatibility with aqueous environments, template leakage, and the presence of heterogeneous populations of binding sites in the polymers that contribute to high levels of non-specific binding. This success is closely related to the technology-driven shift in MIP research from traditional bulk polymer formats into the nanomaterial domain. The aim of this article is to throw light on recent developments in this field and to present a critical discussion of the current state of molecular imprinting and its potential in real world applications.

“…Sample preparation protocols enable: (i) adequate compatibility of the tested sample with the selected analytical technique, (ii) interference elimination when complex samples are analyzed, and/or (iii) adequate sensitivity for determination of analytes at low concentration levels, among others. However, sample preparation methods are often time consuming and, in most cases, they are the limiting step of the overall analytical procedure [1–3].…”

“…Microscale extraction approaches are appropriate non‐exhaustive sample preparation tools for the miniaturization of the analytical procedure while reducing the analysis time and ensuring acceptable preconcentration factors [1]. These methods use low amount of solvent or sorbent material as extraction phase for the isolation of the analytes in the sample [1]. Two main microextraction modes can be distinguished based on the nature of the extraction material, solid, or liquid: solid phase‐based microextraction [4,5], and liquid‐phase microextraction (LPME) [6], respectively.…”

Ionic liquids and derivatives-mainly polymeric ionic liquids and magnetic ionic liquids-have been extensively used in microscale extraction over the past few years. Current trends in analytical sample preparation gear toward linking microextraction approaches with high-throughput sample processing to comply with green analytical chemistry requirements. A variety of high sample throughput strategies that are coupled to both ionic-liquid-based solid-phase microextraction and ionic liquid-based liquid-phase microextraction are herein reported. The review is focused on microscale extraction methods that use (i) custom-made and dedicated extraction devices, (ii) parallel extraction, (iii) magnetic-based separation, and (iv) miniaturized systems employing semi-automatic or fully automatic flow injection methods, related micro/millifluidic devices, and robotic equipment.

“…The most used sample preparation processes are filtration, dilution, extraction, or analyte derivatization. Analytical sample preparation is a field constantly evolving due to the development of novel materials for SPE [6–8], and solvents for LLE [9,10]. Other advances in sample preparation are the development of innovative approaches and devices for the automation of the analytical procedure [5,11–13], opening new possibilities for chemical analysis, or improving existing analytical methods in terms of reproducibility, robustness, and miniaturization.…”

In the last 5 years, additive manufacturing (three-dimensional printing) has emerged as a highly valuable technology to advance the field of analytical sample preparation. Three-dimensional printing enabled the cost-effective and rapid fabrication of devices for sample preparation, especially in flow-based mode, opening new possibilities for the development of automated analytical methods. Recent advances involve membrane-based three-dimensional printed separation devices fabricated by print-pause-print and multi-material three-dimensional printing, or improved three-dimensional printed holders for solid-phase extraction containing sorbent bead packings, extraction disks, fibers, and magnetic particles. Other recent developments rely on the direct three-dimensional printing of extraction sorbents, the functionalization of commercial three-dimensional printable resins, or the coating of three-dimensional printed devices with functional micro/nanomaterials. In addition, improved devices for liquid-liquid extraction such as extraction chambers, or phase separators are opening new possibilities for analytical method development combined with high-performance liquid chromatography. The present review outlines the current state-of-the-art of three-dimensional printing in analytical sample preparation.
