Water is the basis of all life
Essentially, nano scale sciences and engineering or nanotechnolgy are driving scientists to look at the submicroscopic world - the molecules of water in a lake and pores of a filter, for example - to understand the properties of these tiny parts and to find ways to apply them to larger problems.
Nanotechnology is already used in many electronic applications and in biological research. But now, scientists are exploring the possibility of using nanotechnology to purify public water supplies.
Nanotechnology could render water reusable, which is a more feasible alternative, because it could be used to identify and remove contaminants which conventional technology cannot.
According to Dr Mamadou Diallo, director of Molecular Environmental Technology at the California Institute of Technology, nano-water purification methods are the wave of the future.
"We envision that nano-materials will become critical components of industrial and public water purification systems," he writes in a paper published in the Journal of Nanoparticle Research.
