| Abstract: | The utilization of poly(Methylene blue) coated carbon fiber microelectrodes for simultaneously determining of dopamine and ascorbic acid was proposed in this paper.This approach offered several advantages such as simultaneous determination of dopamine and ascorbic acid with high sensitivity and the detected species didn't sully (adsorb) electrodes.More importantly, this analytical process can be performed without deaeration,which was an important condition for in vivo studies. |
