Nanobots

Researchers can steer microscopic machines using magnetic resonance. New nanobots may eventually be able to deliver targeted medication by traversing the body's intricate blood vessels. Researchers in Canada have joined engineered beads to inherently magnetic bacteria, allowing the bacteria to be driven via MRI machines to the desired location in the body. This could represent a breakthrough in targeted delivery of anti-cancer drugs. It is a hint of the possibilities of nanotechnology in medicine.
