Bio -hybrid robots work with biological ingredients such as muscle, plant content, and even fungus with non -biological materials. Although we are very good at working non -biological parts, we always have difficulty keeping organic ingredients alive and well. This is why biological muscle -driven machines have been small and easy instead.
“The lab -growing muscle contract force, the risk of necklasses in thick muscle tissues, and the challenge of integrating biological activists with artificial structures,” says Shuji Techchi, a Japanese professor, says Shuji Techchi. Tekuchi led a research team that built a full -size, 18 cm -long biombrid man with five -powered human muscle fingers growing from a lab.
To keep the muscles alive
Of all the road blocks that prevent us from making a large -scale biometric robot, Nicrosis has been the most difficult to overcome. Mounting muscles in the lab usually mean a liquid medium for the supply of nutrients and oxygen to the seed muscle cells on the pot of patteries or is applied to the gel sorry. Since these civilized muscles are small and ideally flat, nutrients and oxygen can easily reach each cell in the growing culture.
When we try to thicken the muscles and therefore more powerful, the deep buried cells in these thick structures are cut off with nutrients and oxygen, so they die, pass through the nicrosis. In organizations, this problem is solved through a vascular network. But the construction of the artificial vascular network in the lab muscles is still something we can’t do very good. Therefore, Tekuchi and his team had to find their way around the Nicrosis problem. Their solution was Sushi rolling.
The team started organizing each other on the Patri dish as well as thin, flat muscle fibers. This gave all the cells access to nutrients and oxygen, so the muscles turned out to be strong and healthy. Once all the fibers grew up, Tekuchi and his colleagues wandered them into tubes called Mammotas (multiple muscle tissue actors) as they were producing Sushi rolls. “The mammoths were formed by wrapping in a symbolic bundle to improve the contraction by cultivating thin muscle sheets and maintaining oxygen dishes,” said Tekuchi.
