Low Cost Automated Handheld Melamine Detection Device (for Testing Melamine in Milk)

Students of the Indian Institute of Science, Bangalore Dhiraj Indana including his team member S.C.G. Kiruba Daniel, Varun S, Prateek Katare who worked under the guidance of Dr. Sai Siva Gorthi received the Gandhian Young Technological Innovation Award-2017 for developing a prototype of a Low Cost Automated Handheld Melamine Detection Device (for Testing Melamine in Milk).

Device_PhotoEven though a number of kits and devices are available for detecting common milk adulterants like urea, boric acid, water, sugar and detergents, there is hardly any portable device available for the detection of melamine. Till now, bulky instruments like Gas Chromatography (GC), HPLC, GC-MS and LC-MS are being used for detecting melamine which costs between 25 to 50 lakhs rupees, as well as requiring skilled personnel for operation. A fully automated handheld device to detect melamine from milk with integrated milk pre-processing step done using chemical dried cotton is developed. Melamine is finally detected through interference in Silver nanoparticle formation. Both the preprocessing and detection steps are innovative and patented. The cost of the device may be few thousand rupees which is almost 1000 times lesser than the price of existing conventional instruments. The developed device is user-friendly Low Cost Automated Handheld Melamine Detection Device (for Testing Melamine in Milk) which can give the level of melamine adulteration in ppm directly. Thus, the device not only tells the user whether the milk is fit for consumption or not but also gives the exact concentration of melamine in milk. This device fulfills the goal of taking melamine sensing to every household so as to protect every person from melamine adulteration.

For this innovation Dr. R A Mashelkar, Chairperson, Research Advisory Committee, SRISTI and NIF, honored Dhiraj Indana, Department of Nano Science and Engineering, Indian Institute of Science, Bangalore, with the prestigious BIRAC-SRISTI Gandhian Young Technological Innovation (GYTI) Award 2017 at a function held at Rashtrapati Bhawan on March 5.
