Single molecular nanoparticles(SMNPs)integrating imaging and therapeutic capabilities exhibit unparalleled advantages in cancer theranostics,ranging from excellent biocompatibility,high stability,prolonged blood lifetime to abundant tumor accumulation.Herein,we synthesize a novel porphyrin nanocage via a template-directed strategy1,2 and further fabricate it into SMNPs(porSMNPs)through post modification by polyethylene glycol chains.
