Researchers at Stanford University Medical Center developed and tested it in mice.
The implant is activated remotelyand heats the nanoparticles introduced into the tumor. This starts the process of destroying cancer cells. Biologists treated mice with brain tumors for 15 minutes daily for more than 15 days. As a result, they noticed that the mice began to live longer.
Nanoparticles allow targeted treatment onlyon the tumor, so the side effects are much less, especially when compared with chemotherapy and radiation, the authors of the development explain in a new article.
Photothermal treatment, which usesLight for heating nanoparticles in the fight against brain tumors is not something new; however, they can only be used during operations when the tumor is exposed to a light source.
After four years of hard workResearchers have developed a system that generates heat precisely at the site of tumors to destroy them. A wireless implant is implanted between the skin and the skull. Gold nanoparticles are then injected into the tumor through a tiny hole in the skull. The implant emits infrared light that penetrates brain tissue and activates the nanoparticles, which raise the temperature by up to 5°C. Tumors of various sizes can be killed by adjusting the power and wavelength of the light.
