Abstract
Amperometric detection is ideally suited for integration into micro- and nanofluidic systems as it directly yields an electrical signal and does not necessitate optical components. However, the range of systems to which it can be applied is constrained by the limited sensitivity and specificity of the method. These limitations can be partially alleviated through the use of redox cycling, in which multiple electrodes are employed to repeatedly reduce and oxidize analyte molecules and thereby amplify the detected signal. We have developed an interdigitated electrode device that is encased in a nanofluidic channel to provide a hundred-fold amplification of the amperometric signal from paracetamol. Due to the nanochannel design, the sensor is resistant to interference from molecules undergoing irreversible redox reactions. We demonstrate this selectivity by detecting paracetamol in the presence of excess ascorbic acid.

Notes
The factor of 2 appears because in this procedure, I ref ∼ I 1/2 for a device with a symmetric IDE geometry. This is because 50% of the redox species is in the oxidized state, while the other 50% is in the reduced state in the region during the measurement of I ref while they are completely reduced or oxidized during the measurement of I 1.
