In a cartoon called Generator Rex, which was very popular in our country for a while, our main character could use different powers with the nano-robots in his body. In fact, the basis of this idea was found in 1959 by the famous theoretical physicist The theories of Richard Feynman It was based on Feynman suggesting that swarms of microbots floating in the blood could be used to deliver drugs and repair internal organs.

After a 65-year hiatus, scientists discovered these microbots to make it happen It’s one step closer. Engineers at the University of Tokyo have developed a method that allows microscopic structures to function without the need for external energy.

Under normal circumstances, structures in the blood are dragged along due to the velocity of the blood flow. microbots In order to work, it must be able to withstand this current. Single-celled, freely moving creatures were combined with small structures that resembled horse-drawn carriages.

Researchers in Japan have identified fish with a high swimming ability to withstand blood flow. Chlamydomonas reinhardtii used green algae. These structures, which are only 10 micrometers wide, can attract objects five times their size. According to the statement of the designers, this is an important discovery for new machines.

this algin for human consumption There is no problem. The creature, which has two flagella, can move and choose its direction. These structures can reach speeds of 100 micrometers per second.
