In this study, a novel multiwalled carbon nanotubes/polyaniline-polypyrrole@polydimethylsiloxane (MWCNTs/PANI-PPy@PDMS) fiber was prepared by a facile electrodeposition strategy followed by polymer surface modification, and used as the sorbent of in vivo solid phase microextraction (in vivo SPME). The custom-made fiber exhibits better enrichment capacity than three commercial SPME fibers. Ultra-high enrichment factor (438–2659), satisfactory thermal and mechanical stability, excellent matrix-compatibility and anti-biofouling ability render the...
