Nanotube pores hold promise of cutting the cost of desalination substantially

For the first time a bioinspired carbon nanotube (CNT) water filter has been made that can transport water faster than its biological counterparts.1 The work could lead to new desalination membranes and ways to purify water to meet ever increasing global demand for fresh water.
