Researchers from the Indian Institute of Technology, Madras have developed a technology that uses gold and silver nanoparticles to filter pesticides from water. The article says that the new technology will be manufactured by water filtration company Eureka Forbes. In a recent paper, researcher T. Pradeep said, “Water purification systems equipped with nanomaterials and using new kinds of membrane technologies with variable pore sizes as filters could provide people in any area with safe drinking water.” The article says that tests have shown that the nanoparticles are able to adsorb pesticides, reducing their presence to acceptable levels. Pradeep also said, “If any village panchayat approaches us with a demand to fabricate a filter for the community we can even waive the royalty.”
