High-Performance coupled plasmon waveguide resonance optical sensor based on SiO2:Ag film

open access: yesResults in Physics, 2021
A coupled plasmon waveguide resonance (CPWR)-based optical sensor takes advantage of the evanescent wave at a waveguide boundary to excite surface plasmon polaritons, which can link waveguide electromagnetic energy to a surface plasmon wave to enhance ...

Elucidating the signal responses of multi-parametric surface plasmon resonance living cell sensing: a comparison between optical modeling and drug-MDCKII cell interaction measurements. [PDF]

open access: yesPLoS ONE, 2013
In vitro cell-based assays are widely used during the drug discovery and development process to test the biological activity of new drugs. Most of the commonly used cell-based assays, however, lack the ability to measure in real-time or under dynamic ...

Surface Plasmon Resonances in Silver Nanostars [PDF]

open access: yesSensors, 2018
The recent development of silver nanostars (Ag-NSs) is promising for improved surface-enhanced sensing and spectroscopy, which may be further exploited if the mechanisms behind the excitation of localized surface plasmon resonances (LSPRs) are identified.

Surface Plasmon Resonance [PDF]

open access: yes, 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 ...

Laser Nanostructuring for Diffraction Grating Based Surface Plasmon-Resonance Sensors

open access: yesNanomaterials, 2021
The surface plasmon resonance properties of highly regular laser-induced periodic surface structures (HR-LIPSSs) on Si, functionalized with Au nanoparticles (NPs), were investigated. In particular, the spectral dependencies of polarized light reflectance

Development of a combined surface plasmon resonance/surface acoustic wave device for the characterization of biomolecules [PDF]

open access: yes, 2009
It is known that acoustic sensor devices, if operated in liquid phase, are sensitive not just to the mass of the analyte but also to various other parameters, such as size, shape, charge and elastic constants of the analyte as well as bound and viscously
