摘要

Fluidic nanochannels with 1-2 nm in size are functional mimics of protein channels, and have recently attracted significant attention for exploring the transport of ions and molecules in confined liquids. Here we report ion transport in 2 nm deep nanochannels fabricated by standard semiconductor manufacturing processes. Ion transport in these nanochannels is dominated by surface charge until the ion concentration exceeds 100 mM. At low concentrations, proton mobility increases by a factor of four over its bulk value, possibly due to overlap of the two hydration layers adjacent to hydrophilic surfaces. The mobility of K+/Na + ions also increases as the bulk concentration decreases, although the reasons are not completely understood.
