This feature article from Nanowerk, written in collaboration with scientists, provides a short introduction to the role nanotechnology could play in resolving water shortage and quality issues.

The authors describe how nanotechnologies are being used in water filtration, especially nanotechnology membranes incorporating carbon nanotubes and dendrimers. They also examine how nanotechnologies and materials such as zeolites, carbon nanotubes and biopolymers can be used to remove, reduce or neutralise heavy metals and other contaminants that pose a threat to human health. And they briefly discuss the issue of using nanotechnology to develop water disinfectants.
