Scientists have developed nanomodified polymer implants that are compatible with the human organism, dissolve within several years, and even have antibacterial properties. The nanomodified implants may enable restoration of limb functions even after loss of whole parts of the skeleton, which is impossible with existing technology.
Because polymer materials can contain pathogenic microorganisms, they can cause dangerous infections and inflammation, as well as rejection of adjacent tissues. Nanomodified polymer implants can eliminate the microorganisms they bring into the human body, and they can ensure quick osseous fusion. During the fusion, the bone gradually grows through the implant.
As hydrogel- and lyophilic-nanomodified films, the nanomodified polymers can be used to create effective permanent dressings for treating severe burns and wounds. The films cover large areas and protect against pathogens because they contain silver nanoparticles and bentonit, which speeds up the healing process. The healing agent covers the entire wound or burn, so that it acts like second skin.
The use of nanomodified polymer technologies in medicine is promising, but the researchers say additional information is needed on the nanoparticles’ toxicity, which is an important factor in treating humans.
