Cyclic voltammograms in 50 mM phosphate buffer (pH 7.4, 0.02% v/v Tween-80) and 72.5 µM insulin solutions in the same buffer at a 3.0 mm GCE coated with each film type vs. Ag/AgCl (2 M KCl). Scan rate: 50 mV/s. (A) MWCNT cast from DMF; (B) MWCNT/dihexadecyl phosphate electrode; (C) MWCNT/DHP electrode.
