Advances in Fabric Phase Sorptive Extraction

Dear Colleagues,

Fabric phase sorptive extraction (FPSE), a new-generation green sample preparation technique, has drawn considerable interests in recent years among practicing scientists and researchers in many different fields, including analytical chemistry, bioanalytical chemistry, clinical chemistry, food science, environmental chemistry, pharmaceutical chemistry, forensic science, and sports science.

FPSE has uniquely integrated solid phase extraction (exhaustive extraction) and solid phase microextraction (equilibrium extraction) into single, unified sample preparation technology platform. As such, FPSE can be performed in SPE mode, as  well as in direct immersion-SPME mode. However, both the extraction modes offer near exhaustive extraction depending on the logKow of the analyte.  

Unlike conventional sample preparation techniques such as solid phase extraction and solid phase microextraction which only utilize the selectivity of prisine organic polymers or ligands, fabric phase sorptive simultaneously exploits the selectivity of the organic polymer, unique material properies of Si/Ti/Zr chemistries and hydrophilic/hydrophobic properties of the fabric substrate to boost the analyte extraction efficiency.

In addition to substantially simplifying sample preparation, FPSE has eliminated sample pretreatment steps such as filtration, centrifugation, protein precipitation and sample post-treatment steps such as solvent evaporation and sample reconstitution from the sample preparation work-flow.

FPSE opens up a new direction in whole blood analysis without converting into plasma/serum with a far reaching implications in clinical chemistry, metabolomics disease biomarker discovery, phamacokinetics and pharmadynamics studies to name a few.

I take the pleasure to invite you to contribute original research articles and review papers for this Special Issue, ”Advances in Fabric Phase Sorptive Extraction”, which will highlight the advantages of FPSE as a green and simple sample preparation technology over its conventional counterparts.
