Surface Plasmons Imaging Much Easier Than First Thought
LOUVAIN, Belgium, June 7, 2011 — An unusual observation turned into a breakthrough when researchers at Katholieke Universiteit Leuven discovered that surface plasmons leave imprints on the surface of the nanostructures. The result is expected to lead to a new type of high-resolution microscopy for imaging the electric fields of nanostructures. Surface plasmon patterns can be imprinted on metallic nanostructures for subsequent high-resolution imaging with standard surface probe techniques. Nanomaterials tend to acquire...
