A new SWCNT modified gold detector for microchip capillary electrophoresis-electrochemistry is described. SWCNT modified gold electrode displays greatly improved sensitivity and separation resolution compared to bare gold electrode, reflecting the electrocatalytic activity of SWCNT. The SWCNT/Au electrode exhibits low background noise levels. Parameters such as separation voltage and detection potential of the microchip electrophoresis- electrochemistry with SWCNT modified gold electrode were optimized. © Springer-Verlag 2005.
