Maximizing the Surface Sensitivity of LSPR Biosensors through Plasmon Coupling-Interparticle Gap Optimization for Dimers Using Computational Simulations (vol 11, 527, 2021)

Summary: By simulating coupled plasmonic nanosphere and nano-ellipsoid dimers in LSPR biosensors, the optimization of nanoparticle arrangements can enhance sensor sensitivity. Results show that adjusting interparticle gaps and dielectric layer thickness can enhance plasmonic response range and surface sensitivity, resulting in a higher response to molecular interactions.
