A team of scientists led by Yongdo Jeong at the Korea Institute of Science and Technology (KIST) Center for Advanced Biomolecular Detection has developed " According to the researchers, such machines can be used in certain cellular environments, such as cancer, reports Scitech daily..

During the study, scientists focused on the hierarchical structure of proteins, in which the axis of the large structure and units are hierarchically separated.. Therefore, only individual parts can move around the axis.. Most modern nanomachines are designed in such a way that the moving components and the axis of the large structure are at the same level.. That is, the components move at the same time, which makes it harder to control individual parts..

Scientists have made a hierarchical nanomachine by synthesizing and combining gold nanoparticles with molecules that can fold and unfold depending on the environment.. Upon reaching the cell membrane, the nanomachine began to fold and unfold, penetrate it, destroy the cell organelles and cause its apoptosis (death).

According to the researchers, this new method allows to directly kill cancer cells with mechanical movements, without resorting to anti-cancer drugs..

Later, scientists attached a special latch molecule to the nanomachine, which allowed them to control movements in order to kill only cancer cells with their help.. This latch releases the nanomachine only in an environment with low pH, while in the environment of normal cells, where the pH is quite high, the nanomachine does not move..

Previously, Swedish scientists discovered another function of platelets, which manifests itself in the development of oncological processes.. It turned out that these blood elements can prevent the spread of tumors in the body..
