Scientists at the Centre for Nano and Soft Matter Sciences (CeNS), under the Department of Science and Technology, have developed a breakthrough pocket-sized sensor capable of detecting sulfur dioxide (SO©ü)—a dangerous air pollutant often referred to as a ¡°silent threat.¡±
The compact, low-cost device is engineered to identify even trace levels of SO©ü (as low as 320 parts per billion), surpassing the sensitivity of many current commercial gas sensors. ¡°This innovation can serve as a critical early-warning system in environments where exposure to sulfur dioxide poses severe health risks,¡± said Dr. S. Angappane, lead researcher.
