Near-Infrared Emitting Fluorescent BODIPY Nanovesicles for in Vivo Molecular Imaging and Drug Delivery

Near-infrared fluorescent nanovesides were prepared by self-assembly of block copolymer hydrophilic poly(ethylene glycol) boron-dipyrromethenes in aqueous solution. The fluorescence enhancement induced by dissociation of nanovesides 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.
