Effects of fluid slippage on pressure‐driven electrokinetic energy conversion in conical nanochannels
TL;DR: In this paper , the effects of fluid slippage on the pressure-driven electrokinetic energy conversion in conical nanochannels are systematically investigated, and a multiphysical model that couples the Planck-Nernst-Poisson equations and the Navier-Stokes equation with a Navier slip condition is presented to fulfill this purpose.

Small-scale systems for in vivo drug delivery.
TL;DR: Micro- and nanotechnologies are enabling the design of novel methods such as radio-frequency addressing of individual molecules or the suppression of immune response to a release device, but current challenges include the need to balance the small scale of the devices with the quantities of drugs that are clinically necessary.

Power generation by pressure-driven transport of ions in nanofluidic channels.
TL;DR: The experimental study as a function of channel height and salt concentration reveals that the highest efficiency occurs when double layers overlap, which corresponds to nanoscale fluidic channels filled with aqueous solutions of low ionic strength.

Streaming currents in a single nanofluidic channel.
TL;DR: Measurements of the streaming current, an electrical current generated by a pressure-driven liquid flow, in individual rectangular silica nanochannels down to 70 nm in height, show that it is proportional to the pressure gradient and increases with the channel height.
