Micro-machines journey inside animal for first time
In a case of science fiction meeting reality, microscopic "machines" have journeyed inside a living animal for the first time.
The tiny devices delivered a cargo of nano-particles into the stomach lining of a mouse.
The research by scientists at the University of California is published in the journal ACS Nano.
Medical applications for micro-machines include the release of drugs into specific locations within the body.

Not sure I would call these 'machines'. Nice application of targeted chemistry, though.
