Created artificial cartilage on the basis of Kevlar with properties similar to this tissue

Scientists have developed a hydrogel based on Kevlar, which behaves like a natural cartilage. The artificial structure is a mixture of a network of nanofibers Kevlar and polyvinyl alcohol. It is able to absorb water at rest (like real cartilage at moments of inactivity), become extremely durable and withstand external influences, but can also release water under load and becomes elastic.

The material at 92% filling with water becomes as tough and durable as real cartilage. At the same time, when the water is filled at 70%, the material becomes elastic, comparable to rubber. Previous attempts to create artificial cartilage did not allow the creation of a material containing enough water to transfer nutrients to the cells. Because such materials were poorly adapted for use as implants.

Despite such outstanding properties of the new material, it will take some time before its commercial application for medical purposes begins. Researchers hope to patent a new substance and find a company that will take care of its production and practical application. If the material behaves in the patients' body the same way as in the laboratory, this will lead to the appearance of cartilaginous implants, which work just as well as real tissue.
