A micrometer highly sensitive refractive index sensor comprising of double split ring metallic resonator placed above graphene layer is proposed. The sensitivity of the refractive index sensor is measured for hemoglobin biomolecule concentrations. The sensitivity of 5000 nm/RIU (Refractive Index Uni...
