Microchip capillary electrophoresis with a single-wall carbon nanotube/gold electrochemical detector for determination of aminophenols and neurotransmitters
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 …
