“…In all these SBSE-based techniques the extraction process is kinetically controlled being influenced by the sample volume, sorbent dimensions, and stirring speed, and therefore they usually need relatively high volumes of sample or at least a minimal volume to cover the extraction device [39]. Thus, their miniaturization is challenging and they have been widely applied in environmental and food analysis, where sample volume may not be an issue [40,41]. Nonetheless, their applications in biological analysis are much scarcer [42,43].…”

Miniaturization of the analytical process has been a widespread trend, and the sample preparation stage is not exempted from this downscaling. Since the introduction of microextraction techniques as miniaturization of classical extraction techniques, they have become one of the strengths in this field. However, some of the original approaches to these techniques did not fully cover all the current principles of Green Analytical Chemistry. For this reason, during the last years, much emphasis has been placed on reducing/eliminating toxic reagents, reducing the amount of the extraction phase, and searching for new greener, and more selective extractant materials. On the other hand, even though high accomplishments have been achieved, the same attention has not always been paid to reducing the amount of sample, which is essential when treating low‐availability samples such as biological samples, or in developing portable devices. In this review, we intend to give the readership an overview of the advances toward further miniaturization of microextraction techniques. Finally, a brief reflection is made on the terminology used, or that should, in our opinion, be used to term these new generation of miniaturized microextraction approaches. To this regard, the term, ‘ultramicroextraction’ is proposed to refer to those approaches beyond microextraction.

“…Insofar as the analytical method is concerned, several combinatorial methods, including gas chromatography-mass spectrometry [20][21][22][23], liquid chromatography-ultraviolet spectroscopy [24][25][26][27], and liquid chromatography-mass spectrometry [28][29][30][31][32], have been applied to detect parabens. At present, ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) has become one of the most powerful analytical methods for the detection of trace compounds owing to its excellent resolution, which facilitates the identification of trace parabens in environmental samples.…”

Widespread use of parabens in consumer products has resulted in their ubiquitous existence in the environment including sewage, soil, and sewage sludge. Their potential for human health hazards has, therefore, raised significant public concerns. In this work, an effective in-tube solid-phase microextraction device based on a poly(4-vinylphenylboronic acid-co-ethyleneglycol dimethacrylate) was combined with analysis with ultra-high-performance liquid chromatography-tandem mass spectrometry for detecting parabens in sewage and soil samples, with the limits of detection ranged between 0.64 and 1.4 ng/L.Trace parabens in sewage and soil samples were determined, with amounts of four parabens in the range 0.0141-3.78 ng/g, whereas benzylparaben was not detected. Satisfactory recoveries were observed for the five parabens (86.4-113%), with relative standard deviations (n = 5) ranging between 2.1 and 6.0%. The results indicated that the developed method is prospective to expand in environmental monitoring.

“…They are commonly modified to promote interaction with the target compounds. These modifications involve their superficial coating with polymers (e.g., polymeric ionic liquids (PILs) [ 6 ], molecularly imprinted polymers (MIPs) [ 7 ], commercial ones [ 8 ], nanoparticles [ 9 ], nanocomposites [ 10 ], and silanes [ 11 ]. Although the modification implies several advantages, bare biosorbents simplify and speed up the workflow and reduce the environmental impact related to their preparation.…”

This article deepens the potential of pre-cleaned bare wooden toothpicks (pb-WTs) for extracting drugs (antidepressants and acetaminophen) from oral fluid samples. The leaching of the intrinsic compounds from the wood matrix is identified as the main challenge for the final determination of the targets, even when a very selective instrumental technique, such as mass spectrometry, is employed. The pre-cleaning of the WTs is proposed for improving the analytical performance. The number of cleaning cycles depends on the injection mode (direct infusion or chromatography) into the mass spectrometer. The different variables affecting the extraction of selected antidepressant drugs were studied in detail, and the optimum procedure was validated using the two mentioned injection modes. The limits of detection were in the ranges 0.1–0.5 ng/mL and 0.1–0.3 ng/mL for direct infusion and liquid chromatography, respectively. The intra-day precision (expressed as relative standard deviation) was better than 12.1% and 8.6%, for direct infusion and liquid chromatography, respectively. Single-blind samples were used to study the applicability of the method. Finally, as a proof-of-concept, the potential of pb-WTs for in vivo sampling was outlined. Graphical abstract
