Abstract:
The side-by-side assembly of gold nanorods and proteins, particularly human serum albumin, exhibits a distinct chiroptical activity in a wide range of visible and near-infrared wavelengths corresponding to the surface plasmon resonance. The anisotropy factor was the highest in a colloidal solution system and was able to be inverted by an external environment.
