Photocontrollable dynamic chirality in plasmonic nanoassemblies

Reversible photocontrol of dynamic chirality in self-assembly systems is of great importance in exploitations of artificial nanomachines for scientific and industrious applications1-4. In this talk, we present a new method to achieve controllable chiral switching and selection in plasmonic nanoassemblies. We show here how light enables the switching between opposite chiral states of plasmonic dimers, and how can the light polarization and frequency be regulated to achieve a selectable chirality amplification in the grown plasmonic nanoassemblies.
