Amplified electrochemical detection based on redox cycle at a liquid/liquid interface formed in a microchannel
An electrochemical detector chip with a Y-shaped microchannel was fabricated, and an amplification of the detection current based on the redox cycle at the liquid/liquid interface formed in the microchannel was demonstrated. The dependence of the amplification factor on the flow rate of the solutions was studied.
