“…Similarly as for AIRROA, also for SEROA the sergeants-and-soldiers principle was applied, when chiral acids (e.g., tartaric) imposed their chirality on achiral aromatic linkers (such as 2-mercaptopyridine) attached to the silver nanoparticle surface . The reliability was verified with enantiomers for several chiral compounds (Figure ).…”

Resonance Raman Optical Activity (RROA) appeared as a natural extension of the nonresonance branch. It combines the structural sensitivity of chiroptical spectroscopy with the signal enhancement coming from the resonance of molecular electronic transitions with the excitation laser light. However, the idea has been hampered by many technical and theoretical problems that are being clarified only in recent years. We provide the theoretical basis and several examples documenting the problems, achievements, and potential of RROA, in particular in biomolecular studies.

“…The chirality enhancement of the system was based on two mechanisms: chirality induction in the layer adsorbed on the colloid particles according to sergeants-and-soldiers principle via binding and self-assembly of the linkers together with chiral molecules and surface enhancement (SEROA). 97 Fig. 3 The scheme illustrating a variety of supramolecular systems that can be studied using VOA.…”

Plasmonic Polarization Rotation in SERS Spectroscopy

Surface-enhanced Raman optical activity (SEROA) has been extensively investigated due to its ability to directly probe stereochemistry and molecular structure. However, most works have focused on the Raman optical activity (ROA) effect arising from the chirality of the molecules on isotropic surfaces. Here, we propose a strategy for achieving a similar effect: i.e., a surface-enhanced Raman polarization rotation effect arising from the coupling of optically inactive molecules with the chiral plasmonic response of metasurfaces. This effect is due to the optically active response of metallic nanostructures and their interaction with molecules, which could extend the ROA potential to inactive molecules and be used to enhance the sensibility performances of surface-enhanced Raman spectroscopy. More importantly, this technique does not suffer from the heating issue present in traditional plasmonic-enhanced ROA techniques, as it does not rely on the chirality of the molecules.
