IIT Madras Develops 'paper based Portable device' to detect Adulteration in Milk

Current Context: Researchers at IIT Madras have developed a unique device to detect milk adulteration; this paper based portable device can detect milk adulteration within 30 seconds.

• The paper-based portable device can detect several commonly used adulterants, including urea, detergent, soap, starch, hydrogen peroxide, sodium-hydrogen-carbonate and salt, the researchers said.
• The 3D paper-based microfluidic device has a top and bottom cover and a sandwich structure in the middle layer. This 3D design works well for transporting dense liquids at a constant speed.
