Researchers at the Federal Research Center "Krasnoyarsk Scientific Center SB RAS" have developed gold nanoparticles with unique spectral characteristics in the near-infrared region. These particles can be used for hyperthermic chemotherapy of cancer.
Scientists synthesized pairs of linked gold particles. The infrared range is less absorbed by blood, so it penetrates deeper into the tissues of the human body, reaching cancer cells.
The advantage of gold nanoparticles, which are only 22 nanometers in size, is that they are biocompatible - they are not rejected by the body.
According to Alexander Fedorov, Doctor of Physical and Mathematical Sciences, optical radiation is used to heat nanoparticles during hyperthermic therapy. Thanks to this, it is possible to destroy cancer cells by heating them to a temperature above 42 ℃.
Our nanoparticles allow them to be heated at a greater depth inside the body
Krasnoyarsk scientists will continue to work on gold nanoparticles. Now they need to develop methods for controlling them, as well as make the nanoparticles stable.
Earlier, Russian scientists developed the drug "ComboSpas", which stops blood in just 15 seconds.
