Abstract

We demonstrate an ion pump, consisting of a nanochannel with an AC driven asymmetric electrode array. Our system enables us to actively pump ions using a low driving voltage. In all experiments the electrical double layers are overlapping. Via viscous coupling ion pumping is accompanied by liquid pumping. Actuation below 500 mV at 10 Hz results in a liquid velocity of ~10 μm/s, corresponding to an electrical ion current of ~400 fA. Finite element simulations support the experimental data.
