Nanosensor develop by Jamia Millia Islamia’s Researcher to detect Arsenic Level

Researchers of Jamia Millia Islamia’s have developed a nanosensor(a device that measures physical quantities at nano-scale and converts those to signals that can be detected and analyzed.) to detect the amount of arsenic in living cells, the varsity said on Monday.

Mohd Mohsin, Assistant Professor in the Department of Biosciences, with his research team has developed the nanosensor. Arsenic poisoning has been a major concern that causes severe toxicological damages eg., thickening of the skin, darker skin, abdominal pain, and even death.


The developed nanosensor named SenALiB (Sensor for Arsenic Linked Blackfoot disease) can be used to detect and quantify the level of arsenic in living cells without the destruction of the cell. The arsenic level even up to nanomolar i.e 1000000000 range can be detected by this device.

Quantum leap made by scientists in discovering a new state of matter

“The sensor is a simple and reliable approach that provides high-performance measurements of changes in the arsenic concentration throughout the cells non-invasively and with high resolution,” the varsity said.

The work has been published in the prestigious journal “Scientific Reports” recently.
The toxicity level of arsenic can be measured in any type of cell and any given point of time. The nanosensor has been filed for patents.
