Nanotech Devices
Our proposal now is how to activate the devices for nanotechnology, applications are interesting.
With nanotechnology yielding a burgeoning menagerie of microscopic pumps, motors, and other machines for potential use in medicine and industry.
In an advance toward giving humans that control, scientists in The Netherlands are reporting use of an external electrical signal to control an atomic-scale mechanical device that looks like the flippers on a pinball machine.
Their report is scheduled for the Oct. 8 issue of ACS' monthly journal Nano Letters.
In the study, Harold J. W. Zandvliet and colleagues point out that efforts to build ever-smaller mechanical devices have made scientists recognize the difficulty of exerting control over these nanomachines, which are too tiny for any conventional on-off-switch. They describe construction and successful testing of a device, "grown" on a wafer of germanium crystal, that responds to on-off stimuli.
