Chiral molecules absorb in the deep ultraviolet region, making their detection challenging. Recently, “chirality transfer,” where the interaction between nanoantenna structures and chiral molecules induces circular dichroism (CD) signals at the resonance wavelength of the nanoantenna, has attracted significant attention. In this study, we experimentally investigate the chirality transfer between chiral molecules that absorb around 200 nm and silicon nanoparticles exhibiting Mie resonance.
