Nanotubes mimic biological ion channels

Abstract:
Tiny tubes of boron nitride - similar to biological ion channels - could provide an alternative to desalination plants and may even lead to future treatments for cancer and cystic fibrosis, scientists said.

Tamsyn Hilder, a computational biophysicist at Australian National University in Canberra, ran simulations on boron nitride ‘nanotubes', just 1.4 nanometres (nm) long, embedded in a thin membrane of silicon nitride.

She found that the nanotubes let through water but selectively block other particles, as she announced at the International Conference on Nanoscience and Nanotechnology this week in Sydney.
