In this work, we demonstrate a modality of photodynamic therapy (PDT) through the design of our truly dual-functional - PDT and imaging - gadolinium complex (Gd-N), which can target cancer cells specifically. In the light of our design, the PDT drug can specifically localize on the anionic cell membrane of cancer cells in which its laser-excited photoemission signal can be monitored without triggering the phototoxic generation of reactive oxygen species - singlet oxygen - before due excitation. Comprehensive in vitro and in vivo studies had been conducted for the substantiation of the effectiveness of Gd-N as such a tumor-selective PDT photosensitizer. This treatment modality does initiate a new direction in the development of "precision medicine" in line with stem cell and gene therapies as tools in cancer therapy.
