Release Summary

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of atomic-scale structures, such as single molecules and atomic defects. Such capability is important for optical engineering of nanomaterials and surfaces at angstrom scales.
