Metasurfaces for biomedical applications: imaging and sensing …
WebAbstract We present a theoretical analysis for chiral sensing using achiral anisotropic metasurfaces. We derive analytically, and verify numerically, simple formulas that provide insight into the sensing mechanism and explain how anisotropic metasurfaces offer … WebMar 1, 2024 · The advantage of using a racemic metasurface instead of a chiral metasurface is that it can cancel structural CD signals without any decrease in near field chirality or electric field magnitude compared to purely handed arrays . ... , which makes this metasurface promising for extremely low analyte volume chiral sensing . son of the forest cloth
Plasmonic metamaterials for chiral sensing applications
WebBased on our analysis, the proposed meta-structure has a tunable and controllable chiral response due to the tunability of graphene and circular dichroism (CD) was reached to 0.2. In order to evaluate the performance of the THz device in biosensor application, its characteristics in chiral biomolecule (collagen) sensing was analyzed. With an ... WebAug 4, 2024 · Palermo et al. theoretically studied a chiral metasurface and hyperbolic metamaterial enabling both high sensitivity and specificity for molecules sensing. They argued that the helicoidal metasurface could excite surface and bulk plasmon polaritons, reduce the diffusion limit and increase the sensing surface. WebJun 8, 2024 · Computing metasurfaces have shown the extraordinary ability to precisely perform optical analog operations to the input light wave, and therefore exhibit greater potentials toward sensing applications.
