Nanostructured rubber-like material with optimal properties could replace human tissue
Researchers have developed a nano-rubber material with a number of unique properties that can be used as a replacement for cartilage and other human tissues in medical procedures.
There is now a significant demand for materials that can be implanted into the body without side effects. However, many modern substances, such as botex, are toxic and, when administered, there is a risk of infection. Therefore, a team of scientists from the Chalmers Institute of Technology decided to create a new material from already known safe components..
Initially, they planned to get a tough material for bone replacement, so they took the same base as for plexiglass, reworking design and nanostructure. However, unexpectedly, the team found that he was very soft, flexible and elastic, and also lends itself easily processing. This allows it to be given antibacterial properties in a natural and non-toxic way by constructing so that antimicrobial peptides secreted by the body, which are part of the immune system, adhere to the surface.
The properties of the new material make it possible to insert it into the body through an incision of less than a centimeter, or to inject it through a cannula in the form of a viscous liquid, which will take the desired shape already inside the body. The material can also be used for 3D printing, allowing you to give it any shape you want.
Another advantage is the three-dimensional ordering of nanopores, so it can be used for various therapeutic purposes. For example, as artificial cartilage, filler in plastic surgery, for local disinfection of wounds or for catheter tubes.
A team of Swedish researchers recently founded the company to push the entire development and mass production of the new material..
Recall that recently, scientists have also developed a new antimicrobial polymer coating that kills 99.9% viruses, bacteria and spores.
