A near-infrared fluorescent nanovesicles was prepared by self-assembly of block copolymer MPEG-BODIPY in aqueous solution. The fluorescence enhancement induced by dissociation of nanovesicles could be used as a smart imaging and diagnostic tool. This nanovesicle could encapsulate the antitumor drug, and provide a powerful platform for imaging-guided tumor-specific drug delivery and therapy.
