Circularly polarized light imparts a sense of rotation on the electron density in ring‐shaped gold nanostructures . As a consequence, the near‐field enhancement becomes homogeneous on the surface of the nanostructures, thereby increasing the opportunity for interaction with molecules. This type of nanostructured samples can find a broad range of applications in chemical processes where the interaction between molecules and local field enhancements play an important role.
