A study recently conducted by Graphene Flagship partners the University of Strasbourg and CNRS, France, in collaboration with Nanyang Technological University in Singapore, has shown that graphene quantum dots are biodegradable by two enzymes found in the human body.
Graphene quantum dots (GQDs) are tiny flakes usually smaller than five nanometres that have potential for many applications. GQDs are fluorescent, so they can absorb light and then emit it, often at a different wavelength. They are also so small that they can penetrate cells. Together, these properties pave the way to a wide array of applications in bioimaging, biosensing and new therapies - among other potential uses.
