Circularly polarized light can impart a sense of rotation on the electron density in ring-shaped gold nanostructures. V. K. Valev and co-workers show on p. OP208 that the near-field enhancement becomes more homogeneous on the surface of the nanostructures, thereby increasing the opportunity for interaction with molecules. This type of nanostructured samples can find applications in chemical processes where the interaction between molecules and local field enhancements is important.
