The group led by Assistant Professor Hiromasa Niinomi and Associate Professor Tomoya Oshikiri of Institute of Multidisciplinary Research for Advanced Materials, Tohoku University, has proposed the senario that the large crystal enantiomeric excess in sodium chlorate (NaClO3) chiral crystallization on a Mie-resonant silicon (Si) metasurface was caused by enentioselective transportation of chiral crystalline clusters in chiral near-field with enhanced optical chirality to a chiral crystalline embryo by enantioselective optical force generated by the spatial gradient of optical chirality as one possibility by showing the magnitude of the enantioselective optical force capable of transporting the chiral clusters enantioselectively based on electromagnetic numerical simulations.
