Gold nano-ripple structure with potential for bio molecular sensing applications

open access: yesSensing and Bio-Sensing Research, 2016
We introduce a simple and cost-effective scheme for bio-sensing using nano-ripple structures. One dimensional metallic nano-ripple structures formed by gas cluster ion beam irradiation have shown polarization of light as well as localized surface plasmon

Plasmonic Nanostructure Biosensors: A Review

open access: yesSensors, 2023
Plasmonic nanostructure biosensors based on metal are a powerful tool in the biosensing field. Surface plasmon resonance (SPR) can be classified into localized surface plasmon resonance (LSPR) and propagating surface plasmon polariton (PSPP), based on ...

Extremely short-length surface plasmon resonance sensors [PDF]

open access: yes, 2008
The impact of the system design on the control of coupling between planar waveguide modes and surface plasmon polaritons (SPP) is analyzed. We examine how the efficiency of the coupling can be enhanced by an appropriate dimensioning of a multi-layer ...

Plasmon resonance studies of iron coated gold films with and without an applied magnetic field

open access: yesAIP Advances, 2017
Surface plasmon excitations can result from the absorption of light incident on gold films. Adding a ferromagnetic metal, in our case iron, allows the surface plasmon resonance peak energy to be manipulated not only by the free electrons present in ...

Graphene-coated holey metal films: tunable molecular sensing by surface plasmon resonance [PDF]

open access: yes, 2013
We report on the enhancement of surface plasmon resonances in a holey bidimensional grating of subwavelength size, drilled in a gold thin film coated by a graphene sheet.
