Both attractive and repulsive forces can be exerted on nanoscale devices according to Yale University researchers. The forces will be used to manipulate components on micro-electro-mechanical systems (MEMS) as well as on advanced silicon microchips. The team had already demonstrated the attractive force of light, but today announced the repulsive force too. Next the researchers plan to create nanoscale MEMS switches on a chip to demonstrate their techniques utility.
