Cancer radiation therapy with biocompatible quantum dots for simultaneous dose enhancement and counter-metastasis

A method for radiation therapy treatment of cancer cells, the method comprising:

• preparing a radiosensitizer fluid, the radiosensitizer fluid including a plurality of biocompatible quantum dots;
• introducing the radiosensitizer fluid to cancer cells;
• irradiating the cancer cells with the radiosensitizer fluid to promote generation of reactive oxygen species and inhibit radiation-induced enhancement of cell-migration;
• and
• measuring cell migration of the cancer cells following irradiation.

A method for radiation therapy treatment of cancer cells, the method comprising:

• preparing a radiosensitizer fluid, the radiosensitizer fluid including a plurality of biocompatible quantum dots present in an amount of at least 0.2 micromolar;
• introducing the radiosensitizer fluid to human cancer cells;
• irradiating the human cancer cells with the radiosensitizer fluid to promote generation of reactive oxygen species and inhibit radiation-induced enhancement of cell-migration;
• and
• measuring cell migration of the human cancer cells, via electric cell impedance sensing (ECIS), following irradiation.
