Steering a beam of 'virtual particles' to manipulate ultra-small-scale particles in real time

The steady improvement in speed and power of modern electronics may soon hit the brakes unless new ways are found to pack more structures into microscopic spaces. To do this, researchers are looking into precisely steering, in real time, a curve-shaped beam of weird "virtual particles" known as surface plasmons. This technique opens the possibility of even smaller, faster communications systems and optoelectronic devices.
