Meta-Diastereomers Hierarchical Multiscale Chiral Interactions Between Biomolecules and Nanoscale Enantiomers

Dominic J. P. Koyroytsaltis-McQuire, Rahul Kumar, Shailendra K. Chaubey +5

We introduce meta-diastereomers, hybrid systems where molecular chirality (\,nm) and nanoscale chirality (\,nm) combine to create a new hierarchical chiral state wit…

Tuning Dipolar and Multipolar Resonances of Chiral Silicon Nanostructures for Control of Near field Superchirality

Dominic J. P. Koyroytsaltis-McQuire, Rahul Kumar, Tamas Javorfi +3

Chiral materials display a property called optical activity, which is the capability to interact differentially with left and right circularly polarised light. This leads to the ab…
