Umeå University has published a press release of our latest article about "Electrostatically Driven Nanoballoon Actuator" reported in the journal of Nano Letters. Here is a glance of the press release:
Molecular sized machines could in the future be used to control important mechanisms in the body. In a recent study, researchers at University of California, Berkeley and Umeå University show how a nanoballoon comprising a single carbon molecule ten thousand times thinner than a human hair can be controlled electrostatically to switch between an inflated and a collapsed state.
Schematic drawing of two carbon nanotubes, one in inflated state (cylindrical tube to the right) and one in collapsed state (flattened tube to the left). The transition between the two states can be controlled by applying a small voltage which charges the tube electrostatically and thereby changes the state from a collapsed state to an inflated. The applied voltage is visualized by two tip contacts touching each tube. In the image the tubes are connected to two pistons to envision that the phase change of the tubes could set an imaginary nanomachine in motion.
