| Outline of Final Research Achievements |
The detection and therapy techniques of at super-early stage cancer cells by biocompatible marker nanomaterials are desired. In this study, biocompatible and luminescent photofunctional apatite nanoparticles with mesostructures were successfully prepared for the diagnosis and therapy at the cellular scales. As a result, the nucleation and growth of photofunctional species and apatite precursors occurred on supramolecular assembly to form the mesostructred apatite nanoparticles. The ligand molecules that can selectively react with cancer cells were immobilized on the nanoparticles. The nanoparticles exhibit nontoxicity and specifically and effectively bind to cancer cells to resultantly induce the intense photoluminescence. By the exposure to different energy light, the cancer cells completely disappeared, suggesting that the nanoparticles worked only on the cancer. Therefore, this study provided the novel concept of the non-invasive theranotics for cancer diseases.
