New Water Treatment Technology from Stanford University

In the article High Speed Water Sterilization Using One-Dimensional Nanostructures, silver nanoparticles and carbon nanotubes were used to make a cotton fabric which kills bacteria by applying a low voltage across this conductive material.

The research was completed at Stanford University.

The electrical current that helps do the killing is only a few milliamps at 20volts. The power can be supplied by a small solar panel or a couple 12-volt car batteries. The electrical current can also be generated from a stationary bicycle or by a hand-cranked device.

The full paper can be purchased from the American Chemical Society
