Hierarchical multifunctional graphene oxide cancer nanotheranostics agent for synchronous switchable fluorescence imaging and chemical therapy

A nanotheranostics platform was synthesized based on PEGylated graphene oxide–gold nanoparticles and specified with aptamer toward the MUC-1-positive tumor cells. Subsequently, it was loaded with doxorubicin, used for non-invasive fluorescence imaging and therapy of breast and colon tumors. The succ...
