Using the same devious mechanism that enables some bacteria
to shrug off powerful antibiotics, scientists have developed solar-powered
nanofilters that remove antibiotics from the water in lakes and rivers twice as
efficiently as the best existing technology. Their report appears in ACS’
journal NanoLetters.
David Wendell and Vikram Kapoor explain that antibiotics
from toilets and other sources find their way into lakes and rivers, with
traces appearing in 80 percent of waterways.
