Russian scientists use quantum dots in cancer diagnosis

Moscow, June 5 (Prensa Latina) Researchers at Penza State University have developed unique semiconductor nanocrystals that allow more accurate detection of malignant tumors thanks to their interaction with amino acids, the Russian Ministry of Education and Science reported.

The university’s statement, published Thursday by the digital newspaper Gazeta.ru, highlights that,for the first time, the specialists used quantum dots with a complex structure to detect cancer cells .

Their technology is based on the ability of quantum dots to interact with amino acids, which are actively present in the tumor microenvironment.

Professor Vladimir Krevchik, who worked on the project, said that in the human body, the new quantum dots react to charged amino acids when they reach a tumor.

This interaction causes a change in the energy spectrum and the emission of the quantum dots, which allows the presence of tumor cells to be detected using the wavelength of the radiation, he added.

According to the scientist, if an amino acid is located near a quantum dot, it affects recombination radiation, modifying the wavelength, which makes it possible to determine the presence of an object with charged amino acids, i.e., a tumor.

The authors of the development claim that there are no analogues to this diagnostic method in global practice.

This development could significantly boost the use of quantum technologies in medicine.
