Russian scientists at the Scientific Nanotechnology Center of the Russian South Ural University have discovered a new substance to identify cancer cells in the human body, characterized by a low level of toxicity.
According to the tests conducted by the experts at the center on experimental cells, they manufactured new dyes characterized by spot coloring from 900 to 1100 nanometers, and they used for the first time the substances (selenodiazolo) and (pyridazine).
The results with regard to the cytotoxicity of the drug showed that the experimental cell did not experience any harmful effects at all under the influence of the new substance, in particular with regard to the concentration of the dye that doctors can use to color the cells.
Experts stated that such a phosphorous substance found in oncology works to color or illuminate defective cells, and thus, it gives doctors an opportunity to influence them in a targeted manner with the help of laser, radiation, and chemotherapy.
For his part, researcher Timofey Chuvje and leader of the scientific team at the university said: “The pressure on the body of a patient with cancer is still high in any case, so the phosphorus dye must have a minimum level of cellular toxicity, and this new material aims to make the dye safe for cells and develop it as a solution.” “This problem.”
Cytotoxicity refers to the rate of toxic effects in a living cell, and a number of tests are performed to understand this rate. In fact, tests that evaluate by measuring the rate of proliferation and toxic effects in the cell are called cytotoxicity tests.
