The use of TiO2 nanoparticles activated by light and ultrasound has been studied extensively for cancer treatments. For the first time, researchers have shown the nanoparticles can be effectively activated by microwaves for cancer cell destruction - potentially opening new doors for patients fighting cancer. They propose the use of microwaves and TiO2 nanoparticles to induce the production of reactive oxygen species (ROS), which has the potential to be a safer, more effective modality for cancer treatment.
