'Mushrooms' and 'brushes' help cancer-fighting nanoparticles survive in the body

For a number of innovative and life-saving medical treatments, from organ replacements and skin grafts to cancer therapy and surgery, success often depends on slipping past or fending off the body's immune system. In a recent development, aimed at aiding cancer detection and treatment, Drexel University researchers might have found the ideal surface texture for helping microscopic, medical helpers to survive in the bloodstream without being screened out by the body's natural defense mechanisms.
