“…With the merits of easy operation, convenience, celerity, matrix inter-Article Related Abbreviations: EF, enrichment factor; ExE, extraction efficiency; PANi, polyaniline; PDMS, polydimethylsiloxane; SBSE, stir bar sorptive extraction; SPME, solid phase microextraction; sSBSE, spiral stir bar sorptive extraction. ference resistance, high extraction efficiency (ExE), and lowcost, SBSE has been widely used in complex sample analysis [2][3][4]. Nevertheless, there are some problems associated with this technique, such as the abrasive wear of self-prepared stir bar coating and high cost of available commercial coated stir bar, which limited its further development [5].…”
