Microbial robots will help to defeat vascular diseases
The human body has an extremely complex structure. It includes hundreds of different systems and thousands of tissues with their own characteristics.
Therefore, despite the huge progress in medicine, mortality rates remain quite high. Doctors simply can not reach some parts of the body. The future of science is directly related to microbes, able to penetrate into the most remote corners, give maximum information about the violation and deliver drugs directly to the site of inflammation. One of these developments is the microbial robot that can move through the blood vessels.
How useful is the new microbial robot?
Machines are increasingly included in a variety of areas of human life. The most important role is given to technologies of this kind in medicine. Nanorobots can penetrate particularly dense tissues and shells, reaching the epicenter, and providing the necessary diagnostic information. In addition, they can become the key to the treatment of certain diseases. Specialists of the Polytechnic Institute of Lausanne and the Technical university of Zurich jointly developed a new generation of microbots. It can adapt to different types of biological fluids and move through the human circulatory system.
The project details were shared by the head of the research team Selman Sakar. According to him, scientists were guided by the kirigami principle. This is an art from Japan, in which special paper figures are created with the help of scissors.
Nanorobot is flexible, so it is not a problem to move through narrow and ornate vessels.
The development has a special structure, which makes it possible to adapt to different biological fluids. When moving to a more concentrated or viscous medium, the microbot changes shape, which allows it to move just as quickly. At the same time, specialists retain full control over the machine.
The researchers made a microbial robot from a nanocomposite filled with a special material with a high-density polymer mesh. Due to this, the development retains its elasticity even in aggressive environments. Scientists refused touch control and electric power supply. The direction of movement will be set using a magnetic field. Particles have a minimum size, so the microbot will not interfere with changing its shape in the desired situation.
Selman Sakar noted that thousands of microorganisms are known to science, which can change their characteristics depending on the environment where they go.
Including we are talking about the form. This is necessary for facilitating movement against the flow of biological fluids. They inspired a team of Swiss researchers to create a new generation of nanorobots.
Another important advantage of the technology is its cost. Microbots are quite easy to manufacture, and their production requires inexpensive materials. Therefore, their introduction into medicine will not require excessive costs. At the moment, experts are testing the development, and if everything goes well, it may well be adopted by physicians around the world. In addition, the researchers emphasize their own intentions to further improve the design. Thus, the microbial robot will be able to move even in the most complex biological environments.
