A versatile nano-vehicle, quantum dots nano-transformers, smartly transforms its shape in acidic tumor microenvironment to prolong the tumor retention, and then disassembles and releases the encapsulated photosensitizers to “turn on” the imaging contrast. The total drug dose in repeated photodynamic therapy is reduced because one injection is enough for four times of light irradiation.
