Interacting Metal-Insulator-Metal Resonator by Nanoporous Silver and Silk Protein Nanomembranes and Its Water-Sensing Application.

ABSTRACT: Planar and lithography-free metal-insulator-metal (MIM) resonators based on the Fabry-Pérot etalon are attractive for biochemical sensing applications because of their acceptable optical performance and cost-effectiveness. However, injecting analytes into the insulating layer where the optical field is localized (high light-matter interaction) is difficult. Here, planar and lithography-free MIM resonators interacting with their environment are reported. In the MIM, molecules of a liquid can infiltrate the inherent nanopores in the deposited silver nanomembrane and be absorbed into the silk protein hydrogel membrane. The silk layer is swollen when water molecules are absorbed, inducing a large shift in the resonance wavelength. Thus, in this study, the proposed MIM resonator was applied as
