Abstract
Localized surface plasmon resonance (LSPR) principle-based biosensing methods enable the detection of various target molecules. When illuminated by a light source, oscillation of the free electrons occurson the surface of the metal nanoparticles, thus enhancement of the scattering and absorption can be observed. The plasmon decay plays a major role in the signal enhancement from immobilized mole-cules. Therefore, estimating the field enhancement profile is the key to LSPR sensor benchmarking. Here, we compare two techniques utilizing Layer-by-Layer (LbL) and atomic layer deposition (ALD)
