Mimicking a blood vessel to create a 'bridge' to better medicine and precision treatment

Nanotechnology has led to better diagnostic techniques and more effective treatments for a variety of illnesses. Tiny devices measuring between 1 and 100 micrometers—one micrometer is equal to one millionth of a meter—enable scientists to observe cell activity and deliver drugs to individual cells—a breakthrough that is on the verge of revolutionizing precision medicine for treatment of diseases such as cancer.
