Description
Ziyun Jiang and co-authors show that the handshake between light-absorbing molecules and metal nanoparticles changes how the molecules behave, in a 2025 study. When chiral, or handed, molecules sit on plasmonic particles, their interaction with light could serve sensing and quantum uses, but the interface physics was murky. The team built complexes with atomic-level control over how they adsorb on the particle surfaces.
They found that electric charge flows across the interface. That transfer spreads each molecule's excitation over its neighbors and couples them. The shared response to circularly polarized light changed too: peaks shifted, widened, and changed strength in the circular dichroism spectra. Charge transfer counted more than the near-field electromagnetic coupling usually blamed. The authors say the insight gives designers a new lever: shaping the interface chemistry itself to control optical chirality in future devices.
