Surface Plasmon Resonance: An Introduction to a Surface Spectroscopy Technique

Introduction to Surface Plasmon Resonance

Since its first observation by Wood in 1902 [1,2], the physical phenomenon of surface plasmon resonance (SPR) has found its way into practical applications in sensitive detectors, capable of detecting sub-monomolecular coverage. What is surface plasmon resonance? Wood observed a pattern of ‘‘anomalous’’ dark and light bands in the reflected light, when he shone polarized light on a mirror with ...

Localized surface plasmon resonance spectroscopy and sensing.

Localized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles is a powerful technique for chemical and biological sensing experiments. Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes. This review describes recent fundamental spectroscopic stud...

Surface Plasmon Resonance: A Versatile Technique for Biosensor Applications

Surface plasmon resonance (SPR) is a label-free detection method which has emerged during the last two decades as a suitable and reliable platform in clinical analysis for biomolecular interactions. The technique makes it possible to measure interactions in real-time with high sensitivity and without the need of labels. This review article discusses a wide range of applications in optical-based...
