Setup of electrode chips. (A) The electrochemical detectors are composed of electrodes patterned on a glass chip and a PDMS microchannel. The electrode set includes Ag|AgCl reference electrode, IDA working electrode, and Au counter electrode. The microchannel of 35 μm height, 200 μm width and 1 cm length is connected to a syringe pump. (B) Micrograph of the 25-pair Au IDA with 10 μm-wide microbands and 10 μm gaps.
