1 Introduction Circular dichroism (CD) characterized by the differential absorption of left-handed (LCP) and right-handed circularly polarized (RCP) light is an intrinsic property of chiral compounds, which provides a powerful spectroscopy tool for structural and conformational analyses of complex biomolecules [ 1 ], [ 2 ]. However, the CD signals of naturally occurring materials are typically very weak due to their small dipole moments and hence a weak coupling with the incident light, and therefore can be detectable only at high concentrations or large volumes
