Characterizing the physicochemical properties of magnetic nanoparticles by a surface plasmon resonance approach

open access: yesAIP Advances
Magnetic nanoparticles (MNPs) are widely recognized as effective signal amplifiers for surface plasmon resonance (SPR)-based biosensors. Herein, we report that SPR sensors can be a useful tool to characterize the physicochemical properties of surface ...

A Protein Detection Technique by Using Surface Plasmon Resonance (Spr) with Rolling Circle Amplification (Rca) and Nanogold-Modified Tags

open access: yes, 2009
Surface plasmon resonance (SPR) can detect molecules bound to a surface by subtle changes in the SPR angle. By immobilizing probes onto the surface and passing analyte solution through the surface, changes in SPR angle indicate the binding between ...

Plasmonic propagations distances for interferometric surface plasmon resonance biosensing

open access: yesNanoscale Research Letters, 2011
A surface plasmon resonance (SPR) scheme is proposed in which the local phase modulations of the coupled plasmons can interfere and yield phase-sensitive intensity modulations in the measured signal.
