Developed by BITS Pilani, it can be operated by any person

Scientists at the Birla Institute of Technology & Science (BITS) in Pilani have developed a new bio-sensor device to detect arsenic content in drinking water. The device can be operated by a layman and is based on a rare combination of bio-engineering and electronics. The hand-held device, the size of a mobile phone and presently undergoing field testing, promises to be immensely useful for millions of people inhabiting the river basins of the Ganga, Brahmaputra and Meghna in India and Bangladesh reported to be affected by arsenic contamination.
