Nanoparticles are three-dimensional microscopic objects created from various materials such as calcium carbonate, gold, oxides and other substances. They are used in many fields from electronics to medicine. Candidate of Chemical Sciences, Head of the NUST MISiS Laboratory of Biomedical Nanomaterials, employee of the Department of Medical Nanobiotechnologies of the Russian National Research Medical University, they can be used to fight cancer, especially by “burning” the tumor. NI Ministry of Health of the Russian Federation Maxim Abakumov Pirogov.
“A nanoparticle can act as a drug container. Imagine a drug enters the body so easily, then it circulates throughout the body and enters cells both healthy and diseased. Accordingly, we have a number of side effects. Abakumov, once hidden inside our drug container, only the nanoparticle will go.” He’ll get to the ground,” he said.
The ability to direct nanoparticles to the right places in the body appeared relatively recently. Now doctors have developed a number of technologies that allow the deposition of nanoparticles in tumors. They can be helpful in both the diagnosis and treatment of neoplasms.
“For example, magnetic particles can heat up on their own. And if they accumulate in a tumor, then this tumor can be irradiated with electromagnetic radiation, which is harmless to our body, and diseased cells die, ”said the expert.
This strategy is called magnetic hyperthermia. However, there is a certain limitation to this – if the tumor is very large, there may not be enough nanoparticles for it.
“You cannot deliver them uniformly to the tumor. This is not much of a contraindication for the procedure, it will just be low in effectiveness. It will not be possible to destroy the tumor, but it can be partially resectioned,” Abakumov said.
In Russia, this method of fighting cancer is still used only in research laboratories.
