Abstract

Based on the assembly of Au@protein nanoparticles, we enhance and modulate plasmon-coupled circular dichroism (PCCD) by in-situ stretching of biomolecules between plasmonic nanoparticles, achieving a 1.18-degree circular dichroism and 0.2 dissymmetry factor. Unlike hotspot-based methods, our approach enables reversible PCCD switching over 100+ cycles with significant amplitude changes.
