Chirality discrimination
WebOct 7, 2024 · The anisotropy plays a key role in such performance and shows tunable ability in enantiomeric discrimination even when the chirality parameter is complex valued. Most importantly, the physical origin of chiral discrimination stems from the extrinsic chirality of the system, which arises from the mutual orientation of the SPPs and the optical axis. WebElectromagnetic fields with strong optical chirality interact strongly with chiral molecules and, therefore, can be used for enhancing the sensitivity of chiroptical spectroscopy techniques. Besides a short review of the latest results in the field of plasmonically enhanced enantiomer discrimination, this book introduces the concept of chiral ...
