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.

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.

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 nanostructuring for Surface Plasmon Resonance imaging

2011 International Workshop on Biophotonics, 2011
Improving 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.

On-Chip Surface Plasmon Resonance Sensor

Journal of Nanoscience and Nanotechnology, 2008
A novel on-chip micro SPR (surface plasmon resonance) sensor based on an optoelectronic platform has been developed. This research aims for a fully integrated SPR sensor system to achieve a miniaturized, high throughput sensor system. A novel method for design and fabrication of the solid state SPR sensor device has been investigated.

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.

Surface Plasmon Resonance Assay for Chloramphenicol

Analytical Chemistry, 2008
We report a rapid and ultrasensitive surface plasmon resonance (SPR) assay of chloramphenicol (CAP) by using large gold nanoparticles (40 nm) for signal enhancement on a mixed self-assembled monolayer (mSAM) sensor surface. After immobilization of the target antibiotic CAP through its ovalbumin (OVA) conjugates with an oligoethylene glycol (OEG) linker
