What are nano-shells and why are they important?
Nano-shells are a class of nanoparticles characterized by their core-shell structure. The core is typically made of silica, while the shell is composed of gold. These particles can be precisely tuned to absorb or scatter light at specific wavelengths, making them highly versatile. They are particularly important in
photothermal therapy for cancer, where they can absorb near-infrared light and convert it into heat, effectively destroying cancer cells without harming surrounding healthy tissue.
How has her work impacted cancer treatment?
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.
