By taking clever advantage of the interplay between light, electrons on the surface of metals, and heat, researchers at the National Institute of Standards and Technology (NIST) have for the first time created a plasmomechanical oscillator (PMO), so named because it tightly couples plasmons — the collective oscillations of electrons at the surface of a metal nanoparticle — to the mechanical vibrations of the much larger device it's embedded in.

In the late 1990s, Arthur Nozik of the National Renewable Energy Laboratory in Golden, Colorado, and the University of Colorado, Boulder, theorized that if the semiconductors were made out of nanoparticles, they could excite multiple electrons with less photon energy, because less of the incoming energy would be sapped by vibrating atoms in the crystalline lattice.

This is largely because conventional nanoparticles interact only weakly with the applied field, so quite a large dose is needed to generate enough heat to damage the tumor.

Hearts are promising organs for the new technology because introducing nanoparticles into the wide - open spaces of the organ's atria and ventricles presents less of a challenge than incorporating the tiny magnets all throughout more solid structures like brains or livers, according to Kelvin Brockbank of Clemson University and Tissue Testing LLC, one of the authors of the paper who spoke to reporters during a 28 February teleconference.

Up to this point, researchers have gotten the best results with RNAi targeted to diseases of the liver, in part because it is a natural destination for nanoparticles.

The electrically charged gold nanoparticles repel each other, and because they don't touch, no current can flow along the film.

Because the plasmons are confined to the tiny gap, they are more sensitive than light is for sensing the motion of small objects like the gold nanoparticle.

Chemically, nanoparticles tend to be more reactive than larger amounts of the same substance, because they have more surface area and therefore more opportunity to interact with other substances.

Because of their size, nanoparticles exhibit different properties than their bulkier counterparts.

The finding was quite surprising, team member Orlin Velev says, considering that «nothing was expected to happen with waterborne metallic nanoparticles in the AC electric field because the force between these tiny particles is so small.»
