Chiral Plasmonics Using Twisting along Cellulose Nanocrystals as a Template for Gold Nanoparticles.
The right handed twist along aqueous dispersed cellulose nanocrystals allows right handed chiral plasmonics upon electrostatic binding of gold nanoparticles in dilute environment, through tuning the particle sizes and concentrations. Simulations using nanoparticle coordinates from cryo electron tomography confirm the experimental results. The finding suggests generalization for other chiral and helical colloidal templates for nanoscale chiral plasmonics.
