Scientists at the University of Vermont in the US developed the world’s first robots, which is completely built of living cells. This publication reports Science Alert.
The creators called his invention xenobite. Biorobots are tiny beads of submillimeter size, consisting of 500-1000 cells. They are able to move to self-organize and move microscopic “goods” – like medicines. According to scientists, this new class of artificial objects — living, programmable organism.
The developers used a supercomputer and an algorithm that brought together several hundred cells of the skin and heart of the frog Xenopus laevis in different configurations. Researchers asked the required parameters, for example, the mobility and the generated algorithm is suitable for this purpose Assembly. Just threw about a thousand configurations, the most successful of which were chosen with microscopic forceps and electrode.
The cars were moved to the aquatic environment during the week without adding additional nutrients. Skin cells performs the function of scaffolding, and heart muscle cells provided the ability to move.
