IIT Guwahati Develops Nanosensor to Detect Water Pollutants
Scientists at IIT Guwahati have created a tiny sensor to check water for harmful substances.
The sensor uses materials from milk and thymine.
This sensor glows, and when it finds pollutants like mercury and antibiotics, the glow fades.
Mercury and antibiotics can cause health issues if they get into the water supply.
The sensor works in various water samples.
The research is still ongoing to make sure it works well everywhere.
IIT Guwahati researchers developed a nanosensor to detect water pollutants.
The sensor uses milk protein and thymine with carbon dots.
It detects mercury and tetracycline antibiotics in water.
The sensor's glow dims in the presence of contaminants.
It has been tested in various environments, including tap and river water.
