Wireless power implant could help remove brain tumours
Researchers have developed an implant that triggers nanoparticles to kill brain tumors. The research team includes Fulton Schools Assistant Professor Hamed Arami, whose expertise spans bioengineering, nanotechnology, electrical engineering, imaging and neuroscience. The remotely activated implant heats up gold nanoparticles that have been injected into tumors. The nanoparticles then gradually destroy cancerous cells. By adjusting the power and wavelength of light, researchers can target tumors of different sizes and locations in the brain. Until now the photothermal treatment could be performed only during open skull surgery, when the tumor is accessible. The procedure will produce fewer side effects than the use of current chemotherapy and radiation treatments, Arami says.
