Abstract

In-situ measurement of streaming currents in a single nanochannel with femtoliter-scale volumes is achieved using an elaborately designed and fabricated glass nanofluidic chip with probe electrodes embedded within the nanochannel. The device and the method suggest a useful nanoscale tool enabling in situ understanding of the unique liquid properties observed in nanofluidic channels.

Keywords: electrokinetics; in situ measurements; nanochannels; nanoelectrodes; nanofluidics; streaming currents.
