The research group at the Institute for Molecular Science successfully observed the left and right handedness of material structures at the nanoscale, by illuminating chiral gold nanostructures with circularly polarized light and detecting the optical force acting on a probe near the nanostructures. This result demonstrated that it is possible to analyze the chiral structure of matter at the nanoscale using light. Chirality describes the property of a material structure not being superimposable onto its mirror image.
