The rotor that spins on a bubble
Abstract:
What do you get if you take a set of miniature silicon helicopter blades, drop them into a beaker of water and blast them with sound waves? A remote-controlled underwater "bubble rotor" that could be used to manipulate individual cells. Although the bubble rotor itself is 100 times bigger than ordinary cells, if you attach a carbon nanotube shaft to drill into individual cells, you can learn more about how they respond to stimuli, Attinger says.
