Abstract
In this work the importance of optimizing the surface sensitivity of nanoplasmonic sensors is discussed.In localized surface plasmon resonance (LSPR) based sensing, the size, shape and arrangement of the used nanoparticles all affect their sensitivity. We will demonstrate that by careful design and near-field engineering, the plasmon decay length of nanoparticle-arrangements can be fine-tuned, taking into ac-count the size of receptor and target molecules used in the different sensing scenarios. By optimizing the surface sensitivity of the sensors, their performance in small molecule detection can be maximized.
