New submitter BiancaM (3582365) writes "A group of chemists has shown the
power of nanoparticles for closing and healing surgical wounds. Using no more than a paintbrush they are able to close surgical openings as well as classical techniques such as sutures. However in fragile deep tissues such as liver even more remarkable results were found- normally fatal damage to internal organs is repaired in seconds using a nanoparticle glue. The results show that closing after surgery can be faster and simpler using nanomaterials to glue wounds shut."
For something between the above linked abstract and the research paper, there's this write-up at PhysOrg, and a video of the technique in action.
