Abstract As a two-dimensional material at the nanoscale, optical metasurfaces have excellent and flexible field control methods. In particular, application of concept bound states in continuum (BIC) enables to achieve resonance effects with high quality factors (Q factor). comparison plasmonic metasurfaces, all dielectric can effectively reduce Ohmic losses structure. this study, we propose q-BIC metasurface factor (maximum Q 247), which is symmetry-breaking, investigate enhancement effect structure on chirality near-infrared band. simulation experiment, transmission spectra band exhibited differences different light source incidence angles when illuminated circularly polarised varying rotation directions (external chirality). The maximum far-field circular dichroism (CD) achieved was 0.17 0.038 experiment. Subsequently, near-field investigated, has potential increase incident by up 22 times. Furthermore, introduction chiral medium non-chiral results transfer effect, enabling achievement beyond intrinsic capabilities individual substances involved CD = 0.0055). high-Q all-dielectric paves way for plenty applications fields, including sensing, ultra-sensitive analysis biomaterials soft matter.

Modulating the interaction of chiral molecules with achiral plasmonic nanostructures/superstructures is an important means to realize transfer molecular chirality chirality. Especially, adsorption features molecules, such as cysteine (Cys), have been found affect chiroptical responses greatly. Herein, we that Cys modification on gold nanorods (AuNRs) had a remarkable impact rod etching by ferric ions and gave rise unique patterns encoded information characteristics. significantly accelerated bringing Fe3+ surface via Fe3+-COO– coordination. In combination transmission electron microscopy (TEM) characterization, were able decipher Cys-mediated reconstruct surface. Our findings provide etch-based strategy probe spatial distribution surface, which will deepen our understanding mechanisms rational design rules for enhancing
