Osaka Institute of Technology develop new laser-driven robot to deliver drugs faster

A laser engine could someday allow tiny robots to pull 150 times their own weight. At least, that's the implication of new research that has shown how lasers can give tiny drops of water superpowers. The laser technology could someday be used by scientists to deliver drugs to specific areas of the body, scientists claim. Scientists coated millimetre-sized drops of water in a nanometre-scale powder of polypyrrole, a water-repelling plastic which heats up when illuminated. New Scientist reports that the powder coating turned the drop into a liquid marble, with the fluid contained inside.
