South Korean scientists from Pohang University of Science and Technology have developed a medical bioadhesive based on mussels. Patches made from this composition can be used underwater or inside the body to cover injuries to internal organs. The study was published in the scientific journal magazine Advanced Materials (AdvMat).
In the dry state the patch is not sticky, but in a humid environment the composition adheres firmly to surfaces. Experts also learned to control the decomposition time and mechanical hardness of the product by adjusting the ratio of polyacrylic and polymethacrylic acids. This approach made it possible to create an individual adhesive (adhesive) system, taking into account the different structural and biological needs of various organs.
The research team tested three types of bioplasters using them in animal treatments and implantation. The products maintained high adhesion even in highly mobile organs such as the heart and bladder. Researchers have also conducted successful experiments to regulate the dissolution time of adhesive during implantation of electronic devices for muscle regeneration.
Previous scientists tested Pepper patches to treat neuropathic pain.
