Surface Plasmon Resonance [PDF]
, 2020 The sensitivity of an optical measurement is closely related to the light–matter interaction strength. Enhancing the local-field intensity raises the sensor’s sensitivity. The surface plasmon resonance of metal films and the localized surface plasmon resonance of metal nanoparticles enable the subwavelength confinement of the light field, overcoming ...

Ellipsometric surface plasmon resonance
Journal of Biomedical Optics, 2009 We develop a new multifunctional optical biochip system that integrates an ellipsometer with a surface plasmon resonance (SPR) feature. This newly developed biochip biosensor, which we call ESPR for an ellipsometric SPR, provides us with a system to retrieve detailed information such as the optical properties of immobilized biomolecular monolayers ...
