Localized Surface Plasmon Resonance Biosensor Design Optimization with Metal–Insulator–Metal Nanodisk/Nanoring

Material, shape, size, and aspect ratio affect the biosensing capabilities of localized surface plasmon resonance (LSPR) biosensors. In this work, biosensing capabilities of LSPR biosensor with variations in transducer design parameters were demonstrated. The highest sensitivity obtained throughout this research was 4343,67 nm/RIU using palladium nanoarray disks, and the highest FOM of 25 was obtained using silver nanodisk that has diameter of 50 nm.
