Abstract
Multi-wall carbon nanotube (MWNT)-modified glassy carbon electrodes (GCE) were prepared for simultaneous determination of rutin and quercetin. Microbial carbohydrates, α-cyclosophorohexadecaose (α-C16) and succinoglycan monomer M3 (M3) were doped into MWNTs to prepare a α-C16-doped MWNT-modified GCE ((α-C16 + MWNTs)/ GCE) and a M3-doped MWNT-modified GCE ((M3 + MWNTs)/GCE), respectively. The sensitivities of the (α-C16 + MWNTs)/GCE to rutin and quercetin were 34.7 μA·μM-1·cm-2 and 18.3 μA·μM-1·cm-2, respectively, in a linear range of 2 ~ 8 μM at pH 7.2. The sensitivities of the (M3 + MWNTs)/GCE was 2.44 μA·μM-1·cm-2 for rutin and 7.19 μA·μM-1·cm-2 for quercetin without interference.
