Researchers have developed an entirely new engineering approach that enables the control of biological robots made of human lung cells. These microscopic living robots may one day be able to move through the complex body environments to provide the required therapeutic or mechanical interventions.
The study was conducted by researchers from Dr. Xi Rin Laboratory at the University of Carnegie Mellon in the United States, and its results were published in the magazine of Sains Advances on September 26, and the Yurrick Alert website was written about.
Biological robots are human -making microscopic machines, capable of self -movement and can be programmed to perform specific tasks or behaviors.
In the past, enabling biological robots of movement centered on the use of muscle fibers that allowed them to move through contraction and extraction like real muscles.
Movement using cilia
An alternative and innovative operating mechanism can be found using the cilia, which is a hair -like nanopartinal fans, constantly moving the fluid in the body, as in the lungs. But precise control of the shape and movement of these robots was difficult.
The Rain Laboratory created a new standard assembly strategy for the manufacture of trotted robots, through the spatial assembly of the textile balls that the laboratory engineers create from the lung stem cells known as “Agrebots”.
These collected robots can include tissue balls of stem cells with a genetic mutation that disrupts the movement of the cilia in specific areas, allowing controlling their movement.
This technique is useful for a wide range of researchers, including researchers in the field of vital robots, doctors, and medical researchers studying how cilia works in some diseases.
