Angela's idea was to mix cancer medicine in a polymer that would attach to nanoparticles -- nanoparticles that would then attach to cancer cells and show up on an MRI. so doctors could see exactly where the tumors are. Then she thought shat if you aimed an infrared light at the tumors to melt the polymer and release the medicine, thus killing the cancer cells while leaving healthy cells completely unharmed.
So simple.
