The poly(L-Arginine)(PArg)-multiwalled carbon nanotubes (MWCNTs) composite film was used to modify glassy carbon electrode (GCE) to fabricate PArg/MWCNTs/GCE through electropolymerization of L-Arginine on MWCNTs/GCE. The PArg/MWCNTs/GCE exhibited high electro-catalytic activities towards the oxidation of 3,4-dihydroxyphenylacetic acid (DOPAC), uric acid (UA), and ascorbic acid (AA), and could be sensitively used for simultaneous determination of DOPAC, AA, and UA in pH 7.4 phosphate-buffered solution (PBS). The linear ranges were 7 μM to 2.7 mM for DOPAC, 3 μM to 1.2 mM for UA, and 70 μM to 1.4 mM for AA. The detection limits were 1.3 μM for DOPAC, 0.7 μM for UA and 20 μM for AA.
