| Outline of Final Research Achievements |
The objective of this study is to control crystal chirality in chiral crystallization from an aqueous solution by inducing chiral nucleation under chiral plasmonic near-field. We demonstrated that crystal nucleation can be induced under plasmonic near-field by optical trapping of solute molecules in solution driven by electrical field gradient force of plasmonic near-field in low-weight organic molecule-water system. Although it is necessary to confirm reproducibility at this moment, slight chiral bias was observed in the probability of appearance of enantiomorphs when NaClO3 chiral crystallization was induced on chiral plasmonic nanostructures excited by circularly polarized laser. In addition, we found that homochiral state in NaClO3 chiral crystallization can be achieved by inducing the chiral crystallization by bubble generation resulted from laser irradiation to Au plasmonic nanostructures.
