Nanoparticles to Fight Cancer from the Inside
Scientists at Berlin's Charité Hospital have developed a new technique using nanotechnology to fight cancer cells. Tiny iron oxide particles are used to give malignant cells a high "fever" they can't survive. The new procedure involves coating the tiny iron oxide particles with an organic substance, such as the sugar glucose, and injecting them into a malignant tumor. The tumor, which has a fast metabolism and correspondingly high energy needs, greedily sucks up the little particles masquerading as sugar pellets of a sort. Healthy cells, on the other hand, show little interest. The voraciousness of cancer cells proves to be the tumor's downfall.
