In Krasnoyarsk, at the site of the Radiosvyaz NPO, a nanoshop has opened, where they will produce products for new technologies for diagnosing and treating cancer tumors.
One of the developments is related to biosensors. These are special chips with gold electrodes. They are coated with an aptamer, a small piece of DNA that can bind to cancer cells. To check, it is enough to apply a drop of human plasma to the chip. Based on the reaction of the device, the presence of cancer can be determined. For treatment, scientists propose using nanodisks with nickel and gold. Aptamers are also attached to them, which help find cancer cells. After this, the body is placed in a low-frequency magnetic field, and the nanoparticles begin to vibrate and destroy precisely the malignant cells.
Krasnoyarsk scientists call this method magnetic-mechanical microsurgery or “nanoscalpel.” Its difference from chemotherapy is that the effect must be targeted, without damaging healthy cells. Now the technologies are going through the stage of scientific and laboratory research. Towards a new direction NPO “Radiosvyaz” allocated a separate workshop. Now about 250 specialists work there. They are developing nanoscalpels, biosensors for diagnostics and materials for examinations using circulating tumor cells. The project was presented to the chairman of the regional government, Alexei Medvedev.
“We will provide full support at all stages – from entering preclinical studies to state registration of these developments as a finished medical product. And of course, at the stage of further use in medical institutions of the region,” said Alexey Medvedev.
Specialists from the enterprise, the Krasnoyarsk Scientific Center SB RAS and Krasnoyarsk State Medical University took part in the development.
