New technology developed to detect malignant tumors more accurately

The new breakthrough technology is based on a clever working principle: quantum dots are designed to interact with amino acids, which are abundant in the tumor microenvironment.

Researchers at Penza State University have developed unique semiconductor nanocrystals, the Russian Ministryof Education and Science said.

This new technology promises to detect malignant tumors more accurately thanks to their unique ability to interact with amino acids in the body.

This is the first time that experts have used complex quantum dots to detect cancer cells. This breakthrough technology is based on a clever working principle: quantum dots are designed to interact with amino acids, which are abundant in the tumor microenvironment.

Professor Vladimir Krevchik, a key member of the project, explains that when these new quantum dots reach a tumor in the human body, they react specifically to charged amino acids.

This interaction not only changes the energy spectrum but also the wavelength of the radiation emitted by the quantum dots. It is this change in wavelength that is the "signal" for scientists to detect the presence of tumor cells.

According to scientist Krevchik, if an amino acid is located near a quantum dot, it will affect the recombinant radiation, changing the wavelength, helping to determine the presence of an object with a charged amino acid, that is, a tumor.

The authors of this work assert that the research results could significantly promote the use of quantum technologies in medicine./.
