Scientists from the Institute of Nano Science and Technology (INST), an autonomous institute of the Department of Science and Technology have developed an equipment-free fluoride ion detection and quantification in drinking water with the naked-eye. It can be operated by non-experts for household use to evade Fluorosis-based disorders.
- The technology developed by Dr. Jayamurugan Govindasamy and his team involves a push-pull chromophore based on 2,3-disubstituted 1,1, 4,4-tetracyano-1,3-butadienes (TCBDs) that changes color upon exposure to fluoride ion.
- The identified chromophore (C3-phenyl, C2-urea functionalized TCBD) is the result of a systematic study seeded by the Early Career Research (ECR) Award and further supported by the Ramanujan Fellowship grant of DST received by Dr. Govindasamy.
What is Fluorosis?
- Fluorosis is a crippling disease resulting from deposition of fluorides in the hard and soft tissues of body due to excess intake of fluoride through drinking water/food products/industrial pollutants over a long period.
- It results in dental fluorosis, skeletal fluorosis, and non-skeletal fluorosis. Easy detection of fluorides in water can help preventing the public health hazards.
