Scientists Mimic Nature’s Vital Potassium Ion Channel

An international team of scientists, including chemist Xiao Cheng Zeng of the University of Nebraska-Lincoln, has created what is in effect a nanoscale sieve that is very selective in what it will allow to pass through -- and performs in much the same way as the potassium ion channels that are vital components of virtually all living cells. It's also the first synthetic nanotube that possesses a uniform diameter, as well as being self-assembling and hydrophobic, characteristics that could lead to industrial and medical breakthroughs.
