Potential Application of Graphene Quantum Dots

Graphene quantum dots )GQDs( have attracted much attention as a new class of fluorescent carbon nanotubes due to its prominent features and potential use in the fields of environment, optoelectronics and energy. GQDs have some unique features like graphene and GO. Functional groups have included oxygen at the surface and wide active surface; have created active sites on the surface, so that drug molecules can be loaded on to the GQD. Recent exciting advances in the use of GQD, such as sensors, bio imaging, pharmaceutical carriers and solar cells, have been highlighted.
