IIT Madras: Pocket-friendly device to detect adulteration in milk:
- Dr. Pallab Sinha Mahapatra, an Associate Professor in the Department of Mechanical Engineering at IIT Madras, along with Research Scholars Mr. Subhashis Patari and Dr. Priyankan Datta, led this research.
- The 3D paper-based microfluidic device comprises a middle layer with a sandwich structure, a top cover, and a bottom cover.
- This 3D design facilitates the consistent transportation of denser liquids at a steady pace.
- To prepare the device, the paper is treated with reagents and allowed to dry.
- Once dry, both paper layers are attached to both sides of the support, and the covers are then affixed using double-sided tape.
- The design employs Whatman filter paper grade 4, which enables the flow of liquid and can store more reagents.
