Potential of nano rubber material in medicine
In the case of accidents and other serious injuries, it can happen that human tissue is needed to treat these injuries. A new rubber-like material with unique properties has now been developed, which could serve as a replacement for human tissue in medical processes in the future.
In the current study by Chalmers University of Technology in Sweden, the new material was tested as a replacement for human tissue in medical procedures. The results of the study were published in the English language journal "ACS Nano".
Introducing materials into the body is very risky
The new rubber-like material has the potential to change the lives of many people. It can serve as a replacement for human tissue during medical interventions. And there is a great demand for new adaptable materials that are suitable for integration into the body. Because the introduction of materials into the body is associated with many risks.
Material doesn't seem to harm the body
The new material consists exclusively of components, the effects of which have already been sufficiently investigated in the body and classified as safe. The basis of the material is the same as with plexiglass. However, by redesigning the composition and using a process known as nanostructuring, the researchers gave the newly patented material a unique combination of properties.
Their real goal was to develop a hard, bone-like material, but the new material was very soft, flexible, and extremely elastic. It was therefore of no use for use as bone substitute material.
Material is suitable for the production of new urinary catheters
The results showed that the new rubber-like material could, however, be suitable for many other applications that require an unusual combination of properties: high elasticity, easy processability and suitability for medical applications. For example, the first possible application could be in the manufacture of urinary catheters. The researchers emphasize that the material can be constructed in such a way that the growth of bacteria on the surface is prevented.
Surface of the nano rubber material showed antibacterial effect
The structure of the new nano rubber material makes it possible to treat its surface so that it becomes antibacterial in a natural, non-toxic way. This is achieved by sticking antimicrobial peptides on its surface. This can help reduce the need for antibiotics, reports the research team. An important contribution in the fight against the growing resistance to antibiotics.
No major interventions are required
The new material can also be used in so-called keyhole surgery, which could reduce the need for drastic operations and procedures to rebuild parts of the body. And the material can be injected via a standard cannula as a viscous liquid, so that it forms its own elastic structures in the body. However, it can also be shaped into various shapes using 3D printing.
New material could serve as a replacement for cartilage
“There are many diseases in which the cartilage disintegrates and there is friction between the bones, which causes great pain to those affected. This material could potentially serve as a substitute in these cases, ”study author Professor Martin Andersson of Chalmers University of Technology said in a press release.
Material can be filled with medicine
Another advantage of the material is that it contains three-dimensionally ordered nanopores, which can be filled with drugs. This enables localized treatment so that, for example, treatment of the entire body with medication can be avoided, which prevents unpleasant side effects. Since the new material is non-toxic, it is also suitable as a filler in plastic surgery, the researchers conclude. (as)
