Ion transport in nanofluidic channels.

Nanofluidic diodes based on nanotube heterojunctions.

The mechanism of tuning charge transport in electronic devices has recently been implemented into the nanofluidic field for the active control of ion transport in nanoscale channels/pores. Here we report the first synthesis of longitudinal heterostructured SiO(2)/Al(2)O(3) nanotubes. The ionic transport through these nanotube heterojunctions exhibits clear current rectification, a signature of ...

Fast nonlinear ion transport via field-induced hydrodynamic slip in sub-20nm hydrophilic nanofluidic channels

Simulation study of the transport properties of ions through ion channels serving as primary components of a nanobiosensor

Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...

Nanofluidic channels of arbitrary shapes fabricated by tip-based nanofabrication.

Nanofluidic channels have promising applications in biomolecule manipulation and sensing. While several different methods of fabrication have been demonstrated for nanofluidic channels, a rapid, low-cost fabrication method that can fabricate arbitrary shapes of nanofluidic channels is still in demand. Here, we report a tip-based nanofabrication (TBN) method for fabricating nanofluidic channels ...
