Use nano sensors to diagnose cancer early

Iranian scientists at the University of Tehran's Nanotechnology Department have designed a nanosensor that helps early diagnosis of cancer.

According to Dr. Dadmehr, very low levels of DNA in the blood are one of the biggest challenges for researchers in detecting changes and early signs of cancer.

The usual methods currently used worldwide are often based on an increase in DNA levels after initial treatment.

However, in their research, Iranian scientists can detect changes, the first sign of cancer in the correct way through the use of a nano system mounted on one. Fluorescent probe tube.

This system has extremely high sensitivity, can detect DNA levels at 0.3 femtomolar. This is the highest detection rate compared to all other methods currently in use in the world.
