Question

Researchers at which institution recently developed " ArsenSafe ", a portable device capable of detecting arsenic contamination in drinking water without laboratory facilities?

TodaySprint · Accepted Answer

The correct answer is Option C: IIT Bhubaneswar. ArsenSafe is a portable handheld device developed by IIT Bhubaneswar for on-site detection of arsenic contamination in drinking water. The technology was developed by the Sensors and Spectroscopy Research Group of IIT Bhubaneswar in collaboration with Nano Semic Pvt Ltd. ArsenSafe is based on a liquid-gated reduced graphene oxide field-effect transistor (rGO-FET) sensor. The device integrates nanotechnology, reduced graphene oxide (rGO), graphene oxide dielectric layers, and machine learning for water-quality monitoring. Arsenic is a toxic, tasteless, and odorless metalloid whose long-term exposure can cause arsenicosis, cardiovascular diseases, neurological disorders, and cancer. ArsenSafe recorded a maximum sensor response of 500% at 40 ppm arsenic concentration, demonstrating high sensitivity. The device exhibited a response time of 17.4 seconds and a recovery time of 11.76 seconds, enabling rapid field testing.
