Plasmonic sensors provide great sensitivity to minute quantities ofanalytes and provide excellent detection. This sensitivity is crucial for applicationsin biomedical diagnostics, environmental monitoring, and food safety. In thisinvestigation, a plasmonic refractive index sensor based on key ring shaped resonatorconsisting of a microring resonator and two rectangular resonator is proposed. FiniteDifference Time Domain method is used to study the transmittance characteristicsof the sensor. The device exhibits quadruple Fano resonance with highest sensitivityof 2521.7 nm/RIU. Other performance parameters such as FOM (Figure of Merit),Q factor and Detection limit are also been calculated, with values 98.8 RIU−1, 99.6and 0.01 respectively. Additionally, the effects of different geometrical configurationsis also studied, providing insights into the design principles in context of potentialfabrication complexities. Further, the simulated Fano characteristic is validated againstthe theoretical value. The application of the proposed sensor is investigated for differenttypes of analyte such as chemical pollutants and temperature sensing.

This paper introduces a novel plasmon refractive index nanosensor structure based on Fano resonance. The structure comprises a metal–insulator–metal (MIM) waveguide with an inverted rectangular cavity and a circle minus a small internal circle plus a rectangular cavity (CMSICPRC). This study employs the finite element method (FEM) to analyze the sensing characteristics of the structure. The results demonstrate that the geometrical parameters of specific structures exert a considerable influence on the sensing characteristics. Simulated experimental data show that the maximum sensitivity of this structure is 3240 nm/RIU, with a figure of merit (FOM) of 52.25. Additionally, the sensor can be used in biology, for example, to detect the concentration of hemoglobin in blood. The sensitivity of the sensor in this application, according to our calculations, can be 0.82 nm∙g/L.
