| Outline of Final Research Achievements |
We and co-workers discovered that optical voritices twist an organic azo-polymer thin film to establish a single-armed chiral surface relief with a micrometer-scale modulation depth.Such chiral structures act as plasmonic metasurfaces to selectively assign and enhance the chirality of molecules and their aggregations.They will also allow us to provide nanoscale imaging systems with chiral selectivity.
In this research, we demonstrate plasmon-enhanced nearfield induced chiral mass transport of the superimposed azo-polymer thin film around the chiral surface relief formed by optical vortex illumination,for the first time.This result paves the way to develop chiral plasmonic devices, for instance, chiral chemical micro-reactors.
