Surface Plasmon Resonance Biosensing

2009
Surface 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, 2021
We 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 for Proteomics

2011
Surface 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 phase imaging

Applied Physics Letters, 2000
We present a promising optical system and technique for detection, imaging, and visualization of minimal changes, of the order of 10−6 in refractive index, in the near field. The system is based on phase imaging of excited surface plasmons in a conducting layer in contact with a sample.

Localized Surface Plasmon Resonance Biosensors

Nanomedicine, 2006
In 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.
