IIT Guwahati has developed a groundbreaking nanosensor that can detect cancer-causing pollutants in water in under 10 seconds. Created using milk protein combined with the DNA base thymine, this cutting-edge sensor swiftly identifies harmful substances like mercury and certain antibiotics, enabling near-instant water safety checks
Why It Matters
- Rapid detection: With results in under 10 seconds, this nanosensor is a huge leap forward for real-time water monitoring.
- Low-cost materials: Utilizing milk protein and thymine makes the sensor both affordable and widely deployable.
- Health protection: Immediate detection of cancer-causing agents like mercury can significantly improve public health, especially in regions with compromised water quality.
How It Works
The sensor leverages the binding affinity between milk protein and thymine to detect pollutants at the molecular level. Detection is triggered by their reaction to contaminants, visibly signaling presence in just seconds
Broader Context
Water pollution remains a critical global challenge, particularly in developing regions. Conventional testing methods often require lab-based analysis and can take hours or even days. This nanosensor’s rapid, point-of-use capability is a potential game-changer for early-warning systems, environmental agencies, and rural communities.
