In the recent past, researchers have found a way to purify water that is convenient and inexpensive.

·         The team has developed a process whereby a glass rod is coated with a polymer film embedded with silver nanoparticles.

·         This glass stirrer kills bacteria on contact, and can be used several times.

According to a researcher, the silver nanoparticles responsible for anti-bacterial action are synthesized inside the film rather than physically incorporated as in several other methods.

·         This thermal treatment ensures that the film containing the silver nanoparticles is insoluble in water. 

A researcher says that, this is a “proof of principle” but several questions need to be answered before the technology can be extended to practical applications. They are still working to further minimize leaching to make it safer and still cheaper and mechanical stirring may be required to handle large volumes of water.
