Imaging of surfaces by concurrent surface plasmon resonance and surface plasmon resonance-enhanced fluorescence. [PDF]
PLoS ONE, 2010 Surface plasmon resonance imaging and surface plasmon induced fluorescent are sensitive tools for surface analysis. However, existing instruments in this area have provided limited capability for concurrent detection, and may be large and expensive.

Surface Plasmon Resonance: A Versatile Technique for Biosensor Applications
Sensors, 2015 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

Surface Plasmon Resonance Sensors Using Optical Vortices [PDF]
NanomaterialsThis study investigates the change in both the angular position and width of the reflectance minimum of an SPR sensor in the Kretschmann configuration when optical vortices instead of plane waves are used for illumination. An analytical expression of the

Effect of slit width on surface plasmon resonance
Results in Physics, 2019 In this paper, a hybrid resonator composed of an all-metal grating made of copper and a dielectric cavity filled with SiO2 between slits is simulated and calculated by the finite-difference time-domain method (FDTD).

Surface Plasmon Resonance [PDF]
, 2020 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 ...

Localize surface plasmon resonance of silver nanoparticles using Mie theory
Journal of Materials Science: Materials in Electronics, 2023 In this work, the optical properties of silver nanoparticles (AgNPs) were explored using Mie theory compared with the experimental AgNPs using the chemical reduction method. Mie’s theory is suited for accurately evaluating the scattering, absorption, and
