| Research Abstract |
Malignant brain tumors are difficult to remove completely due to their cellularity characteristics with borderless diffusion, thus the eradicating brain tumor at the cellular level is strongly desired to obtain a good prognosis. In this study, we first assessed the efficiency of Quantum Dots (QDs) conjugated with Transferrin (Tf) (QDs-Tf) and hollow nanofibers for specific imaging of tumor cells. As a result, we found that imaging brain tumor cells using QDs-Tf is effective in detecting tumor cells at the cellular level with clinical applications. Moreover, we developed another technique to pick up free electron from QDs and then we comfirned that it could induce tumor cell death. These data suggest that the diagnosis and therapy-integrated medical devices with liposomes containing QDs and hollow nanofibers are useful for the treatment against formidable malignant brain tumors.
