Materials, Devices and Approaches for Organic Microextraction

This issue is now closed for submissions.
More articles will be published in the near future.


Currently, microextraction is mostly an umbrella term encompassing a large number of different techniques. Many of these approaches are based on or derived from the so-called solid-phase microextraction (SPME), a technique introduced in the 1980s by Janusz Pawliszyn.

These different systems have a major feature in common; the use of a small amount of sorbent phase compared to the volume or mass of the sample (i.e., small phase ratios). Depending on the distribution constant of the analyte in the pair (extracting phase/sample matrix), this usually leads to a non-exhaustive but potentially quantitative operation either thermodynamically- or kinetically controlled. Conventional fiber-based SPME using commercial devices is a well-established technique. Microextraction as a sample preparation approach has also become an interesting topic for researchers. Alternative formats of solid- and liquid microextraction devices ranging from typically lab-made schemes to commercial products have been described in the literature, as well as novel sorbents and innovative applications of existing contraptions.

The aim of this Special Issue is to bring together original research articles from researchers exploring new formats and devices for microextraction methods. Moreover, this Special Issue welcomes research discussing novel sorbents such as nanomaterials, magnetic particles, biomimetic sorbents, etc. Submissions should include the application of microextraction methods in different industries (e.g., agriculture, food, pharmaceutics, and the environment). Review articles covering new techniques, devices, and classes of sorbent materials are also highly encouraged.

Potential topics include but are not limited to the following:

  • Modern approaches in solid-based microextraction techniques
  • Modern approaches in liquid-based microextraction techniques
  • Strategies for coupling solid-phase microextraction with analytical instrumentation
  • Smart materials in solid-phase microextraction
  • Development of novel materials for solid-phase microextraction fiber coatings
  • Microfluidic chip-based microextraction
  • Green approaches in microextraction
  • Current advances in sorbent-based microextraction techniques
  • Novel applications in targeted and untargeted analytical procedures
  • Future trends in microextraction techniques
