N. Roostaei, S. M. Hamidi
In this study, an all-dielectric achiral etalon-based metasurface proposed and experimentally investigated for the glucose sensing application. For this purpose, all-dielectric metasurfaces based on etalon nanostructure have been fabricated using the soft nano lithography method and also a flow cell channel has been designed and fabricated for glucose sensing using the proposed all-dielectric nanostructure. Finally, glucose sensing based on circular dichroism (CD) spectroscopy was investigated using the sensing chip based on all-dielectric metasurface. In addition, the proposed nanostructure was simulated using the finite-difference time-domain (FDTD) method and a good agreement between the experimental and simulation results has been achieved. Therefore, proposed sensing chip can be useful for sensing applications of the glucose or other biological fluids.
