Indigenous Sensor to detect Arsenic Contamination

  • An Indian scientist from the National Agri-Food Biotechnology Institute (NABI), Mohali, has developed an ultra-sensitive, easy-to-use sensor for detecting arsenic contamination in food and water samples in 15 minutes.
  • Developed on mixed metal (cobalt/molybdenum) based metal-organic frameworks, it can detect arsenic from 0.05 ppb to 1000 ppm.
  • The sensor is highly sensitive, selective, involves a single step, and is applicable for various water and food samples. It can be easily operated by a common man by just correlating the colour change (on sensor surface) with the standard labels.
  • It can be tested with three modes:
    1. spectroscopic measurements
    2. colour intensity measurement with ....
