Controlled with a magnetic field

Controlled with a magnetic field, units of plastic particles on a microchip function as mixers and pumps – familiar Sometimes physicists resort to tried and modeling tricks. Scientists at the Max Planck Institute for Metals Research, Stuttgart University and the Colorado School of Mines have micromachines using the same trick that model makers to ships in a bottle where the masts and rigging of the sailing ship are not built to use up, it is in the bottle . Link in the same way, the scientists, the valves, pumps and agitators of a microlaboratory a micro device on a chip. To do this, they make colloidal particles – tiny magnetizable plastic spheres – as components into the channels on the chip. A rotating magnetic field is used to components components into larger aggregates and set them into motion as micromachines. , December 2008).
