Dr. Halas's research in nano-shells has significantly advanced the field of cancer treatment. By leveraging the unique optical properties of nano-shells, it is possible to target and destroy cancer cells with minimal side effects. This is achieved through a process called photothermal ablation, where nano-shells are injected into the bloodstream and accumulate in the tumor. When exposed to near-infrared light, these nano-shells generate heat, selectively killing cancer cells while sparing healthy cells.
