A multifunctional ICG-FA-PPD nanostructure is constructed by a facile self-assembly method through the negatively charged indocyanine green (ICG)- and positively charged folic acid-modified PEI-PEG-gadoteric acid (FA-PPD). The resulting ICG-FA-PPD is not only able to be used for targeting tumors, magnetic resonance imaging (MRI), and near-infrared imaging, but, more importantly, it enables photodynamic therapy for tumor.
Keywords: imaging; magnetic resonance imaging; multifunctional nanoprobes; near-infrared imaging; photodynamic therapy.
