"Quantum dots made from graphene could be used to treat the inflammatory bowel disease ulcerative colitis, a study in a mouse model has found. Graphene quantum dots (GQDs) effectively regulated the excessive immune response that is characteristic of ulcerative colitis, reducing intestinal inflammation and preventing tissue damage. ... they reduce intestinal inflammation in mice models of ulcerative colitis by suppressing excessive T cell activity. They also found that the GQDs switch the macrophages involved in the inflammatory response to a different type of macrophage that regulates the immune system. GQDs appear to “help maintain a homeostatic balance in the immune system ...
their known powerful antioxidant effect and ability to scavenge reactive oxygen species, which helps reduce inflammation, and their random, non-universal structure that seems to stop them provoking an immune response ...
The GQDs showed negligible toxicity and were naturally cleared from the mice. “We increased the concentration up to 100 times more than the therapeutic condition, and all the mice survived ..."
