CeNS develops a compact solid-state sensor to detect the heavy metal ions in water

Centre for Nano and Soft Matter Sciences (CeNS) has developed a compact solid-state sensor to detect the heavy metal ions in water. It is a portable device which can help onsite detection in remote areas.
 
Heavy metal ions such as lead, mercury and cadmium pose severe potential threats to living beings as they can easily be accumulated in the body and cannot be detoxified by any chemical or biological processes. The health hazards associated with heavy metal ions in water demands the development of efficient and portable sensors for rapid onsite detection of these ions. There is an urge to develop visual sensors, which can effectively detect heavy metal ions rapidly (within seconds) under ambient conditions.

A team of researchers led by Dr. Pralay K. Santra at Centre for Nano and Soft Matter Sciences have developed a compact solid-state sensor to detect the heavy metal ions, e.g., lead ions (Pb2) down to 0.4 parts per billion (ppb) for efficient onsite detection.
