Blood vessels are highways through the body. They can transport drugs to cancer cells, but finding the appropriate ramp to exit the vessel can be tricky.

This image shows a network of blood vessels (green) and collagen (purple) infused with gold nanorods (yellow) inside a living tumor. When researchers heat the particles with near-infrared light, the blood vessels become leaky, making it easier to deliver a therapeutic cargo to its final destination. Because blood vessels provide a universal transport system, such combination therapy has widespread implications for treatment, regardless of cancer type or specific drug needed.
