Recently, a research team at the Charles Sutton Institute of the National Academy of Sciences (CNRS) assembled thousands of nanomachines to produce coordinated contractile relaxation like muscle fibers with an extension of about 10 microns. Related papers are published on the Applied Chemistry website.
The "nano machine" created by nature is a biomolecule composed of extremely complex proteins that participate in the basic life functions of living things, such as transporting ions, synthesizing ATP (energy molecules), and cell division. Our muscle movement is also controlled by the coordinated movement of thousands of these protein machines, a protein machine that has a range of only about 1 nanometer. However, thousands of these tiny effects are combined, and the telescopic motion is magnified to perfectly coordinate various athletic behaviors.
In the past few years, synthetic chemists have made dazzling progress in the field of artificial nanomachines. More and more research has begun to turn to their mechanical properties, but how can we make many nanomachines coordinate in time and space yet? solve.
Now, the research team led by Professor Nicholas Giuseppeni of the University of Strasbourg, France, has successfully synthesized a long polymer chain that combines thousands of nanomachines through supramolecular bonds. Nanomachines can produce linear stretching motions of about 1 nanometer. Under the influence of pH, their simulated motion can cause 10 micron contraction or relaxation of the entire polymer chain, so the various movements are correspondingly magnified 10,000 times, just like in muscle tissue.
This nano-polymerized chain was accurately measured by biometric methods at the University of Diderot's Materials and Complex Systems Laboratory.
The researchers point out that this result will open up broad prospects for many applications, such as micro-robots, nano-information storage, synthetic muscles, etc. These assembleable nanomachines can also be used to design other materials with novel mechanical properties.
