(PhysOrg.com) -- Metallic nanoparticles and other structures can manipulate light in ways that are not possible with conventional optical materials. In a recent example of this, Rice University researchers discovered that ...
(PhysOrg.com) -- Try to picture putting some atoms under a microscope. Even if you could pick them up, put them on a slide and get them to stay still, you still could not see them with even the most powerful optical microscope.
