Nanomedicine offers great promise to solve healthcare problems using nanotechnology. Theranostics provide imaging/diagnosis and therapy simultaneously. Novel agents that target both the neuroinflammation and neu-rodegeneration component of multiple sclerosis (MS) are required. Progress has been achieved in developing smart, surface decorated nanoparticles that effectively transport the therapeutic drug into the central nervous system (CNS). Graphene quantum dots (GQDs) can be traced in vivo by fluorescence imaging due to their unique optical properties. They can also traverse the blood-brain barrier (BBB) and deliver drugs into the CNS. More-over, GQDs have low cytotoxicity and higher biocompatibility. Therefore, GQDs can be utilized to design novel multifunctional nanocarrier theranostic tools for MS.
