Nanoparticles are injected directly into cancer tissues, distributed throughout the tumor, and enter cancer cells, destroying their DNA without affecting other organs
Scientists from the Department of Nuclear Medicine and Tracer Dynamics at Osaka University have developed a new system for targeted cancer radiotherapy, which uses astatine-211-labeled gold nanoparticles
Brachytherapy is a cancer treatment method that uses sealed radioactive sources called "seeds" to be directly implanted into the patient's body
Now, a team of scientists led by Osaka University uses "nanoseeds" of gold nanoparticles containing radioisotopes to ensure that the radiation is limited to cancer cells
Using rat or mouse models, nanoparticles are injected directly into tumors
