The flow of water can be controlled through carbon nanotubes membranes and that too with a superb level of precision. This could lead to discovery of a technology which will be able to convert salt water into pure drinking water in a quick manner or one could even separate specific strands of DNA from biological jumble. Nikhil Koratkar, Associate professor, Rensselaer said: We have, at a very fundamental level, discovered that there is a new mechanism to control water transport. This is the first time that electrochemical means can be used to control the way that the water interacts with the surface of the nanotube. Nanotube membranes have always caught the attention of researchers due to their high selectivity which enables to filter out small impurities and other materials such as DNA from high water content. The researchers of Rensselaer used low voltage electricity for manipulating the water flow through nanotube and control of water movement has never been controlled earlier with such level of precision before.
