Carbon nanotube/polyurethane modified hollow fiber‐pencil graphite electrode for in situ concentration and electrochemical quantification of anticancer drugs Capecitabine and Erlotinib

Abstract: A sensitive electrochemical sensor has been designed for in situ preconcentration and determination of anticancer drugs Capecitabine (CPT) and Erlotinib hydrochloride (ETHC) based on a pencil graphite electrode modified with multivalued carbon nanotube—polyurethane (MWCNT‐PUFIX) nanocomposite that was supported with a piece of polypropylene hollow fiber (HF‐PGE). The electrochemical behavior of CPT and ETHC on the MWCNT‐PUFIX/HF‐PGE modified electrode was investigated by differential pulse voltammetry (DPV) te… Show more

“…No differences were observed between the determinations of AAP and AA alone or simultaneously [136]. Similarly, by employing DPV, it was possible to quantify capecitabine and erlotinib hydrochloride for the MWCNT/PU/HF-PGE [133] and ifosfamide and itoposide for the Au/Pd@rGO@P(L-cys)/PGE [87]. CAdS-SWV detection of flutamide and irinotecan (Table 1) [22] or flutamide and cyproterone (Table 3) [66] in mixtures were reported for the bare or nanoacetylene black-modified PGEs, respectively.…”

“…Other modified PGEs were manufactured by dip [17,61,69,87,88,90,92,127,132,133] or spin coating [48,[50][51][52]125,126,134]. Drop coating was applied to produce Mo 5 O 8 /PGE [34], Trypan blue-modified PGEs [44], different CNT-modified PGEs [47,57,58,68], or PGEs covered with various modifiers [41,49,62,65,135].…”

“…Eshaghi et al [ 140 ] recently developed a biosensor for the technique works best of the anticancer drugs capecitabine (CPT) and erlotinib hydrochloride (ETHC). The nanostructured sensor was built on the surface of PGE using MWCNTs and PU as a nanocomposite.…”
