Boron Nitride Nanotubes Selectively Permeable to Cations or Anions

Hilder, Tamsyn; Gordon, Daniel; Chung, Shin-Ho

Description

Biological ion channels in membranes are selectively permeable to specific ionic species. They maintain the resting membrane potential, generate propagated action potentials, and control a wide variety of cell functions. Here it is demonstrated theoretically that boron nitride nanotubes have the ability to carry out some of the important functions of biological ion channels. Boron nitride nanotubes with radii of 4.83 and 5.52 Å embedded in a silicon nitride membrane are selectively permeable to...[Show more]
