Researchers in Zurich have developed a method by which they can deploy gold nanoparticles to a cancerous tumor in order to kill the cancer cells. By combining iron oxide nanoparticle fragments within the gold nanoparticle shell, they can steer the particle directly to the tumor of target. By using a superparamagnetic based particle, researchers were able to utilize light at a particular frequency to activate the nanoparticles ability to kill the cells. Read more here.
