Induced circular dichroism of achiral dielectric elliptical hole arrays with a monolayer borophene film

Abstract

Induced circular dichroism (ICD) is widely used in miniature polarizers, molecular detection, and negative refractive index media. However, enhancing and dynamic regulation of ICD signals of achiral nanostructures in the...

Active Control and Sensing Application of Ultra-Narrowband Circular Dichroism in Multilayer Chiral Nanorod Arrays

“…Because enantiomers of chiral molecules often exhibit different behaviors in biological processes, the detection and differentiation of chiral molecules are of utmost importance in analytical chemistry, biology, and pharmacology. When a chiral structure interacts with the light of opposite handedness, various chiroptical effects can be generated, such as circular dichroism (CD), 3 asymmetric transmission, 4 and negative refraction. 5 Chiral structures manifest different absorbance under the excitation of left-hand circularly polarized (LCP) and right-hand circularly polarized (RCP) light, and their difference is defined as CD.…”
