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 ...

Surface Plasmon Resonance Biosensing
CLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009Surface plasmon resonance (SPR) biosensors belong to label-free optical biosensing technologies. The SPR method is based on optical measurement of refractive index changes associated with the binding of analyte molecules in a sample to biorecognize molecules immobilized on the SPR sensor.

Parametrically resonant surface plasmon polaritons
Optics Letters, 2021We present the theory of parametrically resonant surface plasmon polaritons (SPPs). We show that a temporal modulation of the dielectric properties of the medium adjacent to a metallic surface can lead to efficient energy injection into the SPP modes supported at the interface.

Surface Plasmon Resonance Multisensing
Analytical Chemistry, 1998We have demonstrated the feasibility of surface plasmon resonance (SPR) multisensing by monitoring four separate immunoreactions simultaneously in real time using a multichannel SPR instrument. A plasmon carrying gold layer, onto which a four-channel flow cell was pressed, was imaged at a fixed angle of incidence.

Surface nanostructuring for Surface Plasmon Resonance imaging
2011 International Workshop on Biophotonics, 2011Improving the performances of a sensor is a prominent objective in developing innovative for clinical applications. Sensitivity is key features for a biosensor such applications. An improvement in sensitivity is reported when nanoparticles (NPs) are exploited for functionalizing the interacting surface.

Surface Plasmon Resonance for Proteomics
2011Surface plasmon resonance (SPR) is a well-established label-free technique to detect mass changes near an SPR surface. For 20 years the benefits of SPR have been proven in biomolecular interaction analysis, including measurements of affinity and kinetics.

Surface plasmon resonance for sensing
2012 12th International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD), 2012We design a structure consisting of Ag strip pair arrays embedded in the background material to achieve localized surface plasmon resonance. Numerical simulation shows that one of the transmission dips of the structure is very sensitive to the background materials, which can be used to achieve high performance sensors.

Bioanalysis with surface plasmon resonance
Sensors and Actuators B: Chemical, 1991Abstract Research and development work has made surface plasmon resonance (SPR) into an accurate, sensitive and fast method with several bioanalytical applications. The first commercial instrument has also recently been introduced on the market. The present contribution reviews the use of SPR for biospecific interaction analysis and describes a ...

Localized Surface Plasmon Resonance Biosensors
Nanomedicine, 2006In this review, the most recent progress in the development of noble metal nano-optical sensors based on localized surface plasmon resonance (LSPR) spectroscopy is summarized. The sensing principle relies on the LSPR spectral shifts caused by the surrounding dielectric environmental change in a binding event.
