A nanofluidic power source that converts Gibbs free energy in the form of an ion-concentration gradient into electricity with single ion-selective nanopores is demonstrated (a). The power output from individual nanopores approaches tens of picowatts (b). A theoretical description is proposed to explain the power-generation mechanism and ion-transport behavior within the nanofluidic structure.
