AB  - 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 fiber attractive as 
      in vivo sampling probe. Combining in vivo SPME with gas chromatography-mass 
      spectrometry (GC-MS), a convenient and sensitive method was successfully 
      developed for the rapid determination of pesticides (hexachlorobenzene, 
      chlorothalonil, fipronil, chlorfenapyr) in garlic. Under the optimal conditions, 
      the proposed method displays relatively wide linear range (three or four orders 
      of magnitude) with a coefficient of determination above 0.9944 both in the 
      standard solution and spiked homogenized garlic samples, respectively. Low 
      detection limits from 0.38 to 1.90 ng g(-1) were obtained in homogenized garlic 
      samples. Relative standard deviations (RSDs) less than 15.5% and recovery between 
      84.0% and 108.2% indicate satisfactory precision and accuracy of the method. In 
      summary, a promising non-lethal method based on in vivo SPME-GC-MS is developed 
      in this study, which provides a green, efficient, economic and rapid strategy for 
      the determination of trace pesticide residues in edible plants.
