The students of Shivaji University viz. Prashant Savalkar and Rhutuja Mandavkar are the two young scientists who have disintegrated silver metal with the help of ‘gomutra’ of native ‘Geer’ cows, making silver nanoparticles from the same. It has been found that such nano-silver particles can be used for the purification of water that has been contaminated with effluents thrown by the textile industry, making the water strongly poisonous.
