A wire thinner than a human hair designed to navigate tiny blood vessels in the brain has been built by scientists. Researchers also tested the technique by seeing if it could navigate the tiny blood vessels of a rabbit ear. In a video accompanying the study the researchers show how the new device flows through tiny tubes in a lab which replicates the network of blood vessels in the body. Researchers also tested the technique by seeing if it could navigate the tiny blood vessels of a rabbit ear. Nine ears were used and the vessels criss-crossing the ears were filled with ink to track where the wire was.
