IIT Madras develops cheap and portable device to check milk adulteration in 30 seconds-Education News

IIT Madras researchers have developed a cost-effective and portable 3D paper-based device that can detect milk adulteration in just 30 seconds.

Unlike conventional laboratory-based methods, this new technology can be used at home and requires only a millilitre of the liquid sample to test for adulterants. The device can detect various commonly used adulterating agents such as detergents, soap, hydrogen peroxide, urea, starch, salt, and sodium-hydrogen-carbonate, among others. The research was led by Dr. Pallab Sinha Mahapatra, Associate Professor in the Department of Mechanical Engineering at IIT Madras, along with research scholars Subhashis Patari and Driyankan Datta. They co-authored a research paper that has been published in the peer-reviewed journal Nature.
