Nature-mimmetic chiroptical metasurface has become a challenging flat optics research theme to apply stereochemistry, molecular biology, crystallography, and further secure quantum communications. In this article, chiral metasurfaces transferred from commercial optical grating were fabricated by using a polydimethylsiloxane (PDMS) film, in which the chirality of the metasurface film was readily tuned to be left- and right-handed by modulating the angle (θ) between the curvature vector and the grating direction, i.e., blaze arrow. Furthermore, a fingerprint – transferred PDMS metasurface with Au coating was prepared to investigate nature-induced chirality and surface plasmon resonance (SPR). Indeed, the fingerprint-transferred metasurface showed unique chiroptical SPR property, induing surface enhanced Raman scattering (SERS) effect to monitor chiral molecules. It is probably ascribed to the grating-like pattern and curvature of the PDMS film transferred the human thumb, similar to the as-designed grating. It is probable that these results will open a novel approach to produce facile chiral metasurfaces.
