Tiny robots that get into our bodies for medical interventions



A new wave of innovation in the field of medicine is what could augur the implementation of microscopic-sized robots. With the help of these robots, doctors would have the possibility to access specific internal regions of the human body without requiring the application of invasive procedures.

Also, these tiny-sized robots could serve as a means of transporting substances to a specific region of the body such as drugs or also genes. This would help explore new alternatives when it comes to treating various medical conditions.

Recently researchers from the ETH in Zurich and the Helmholtz Institute of Erlangen-Nurnberg for Renewable Energy carried out the development of microrobots and nanorobots. For its operation, the locomotion of creatures such as bacteria and sperm was taken as a reference.



According to what is published in an article for the journal Nature Machine Intelligence, these robots have been endowed with the ability to move against the current. This would allow them to move in the opposite direction to fluids such as blood circulating inside the human body.

Thus, these robots would be a promising solution for medical interventions. Developed by Daniel Ahmed, lead author of the work, and his colleagues, these wireless micro/nanorobotic systems can operate smoothly in conditions where there is no slippage.

Instead, they respond to stimuli generated by externally activated acoustic and magnetic fields. In this way, robots can move upwards through blood flow to release small drug molecules to regions of the body whose access is difficult.

By combining both fields (acoustic and magnetic) the robotic system created by the researchers could be useful to overcome some faults generated by other artificial micrometers that work around unique performance techniques.

Also, considering that these micronanorobotss act on fields applied outside the body would not require an installed power supply or sophisticated and expensive components.
