Filter Purifies Water 80,000 Times Faster
The larger pore spaces in Cui's filter also keep it from getting clogged, which is a problem with filters that physically pull bacteria out of the water.
The researchers already knew that carbon nanotubes were good electrical conductors, so the researchers reasoned the two materials in concert would be effective against bacteria.
"This approach really takes silver out of the folk remedy realm and into a high-tech setting, where it is much more effective," said Heilshorn.
The amount of silver used for the nanowires was so small the cost was negligible, said Cui.
Still, they needed a foundation material that was "cheap, widely available and chemically and mechanically robust." So they went with ordinary woven cotton fabric.
"We got it at Wal-mart," said Cui.
"With one filter, we can kill 98 percent of the bacteria. For drinking water, you don't want any live bacteria in the water, so we will have to use multiple filter stages," said Cui.
The study will be published in an upcoming issue of Nano Letters.
