Abstract
The use of surface plasmon resonance measurements for the microscopical imaging of surfaces and thin films has been investigated. Theoretical results are presented for sensitivity optimization and focussed beam measurement. Experimental results are presented for scanned beam and plane-wave imaging of silver surfaces and superimposed dielectric layers. Thickness sensitivity of about 3 angstroms has been achieved, with lateral resolution better than 20 microns.

Bimetallic Layers Increase Sensitivity of Affinity Sensors Based on Surface Plasmon Resonance

TL;DR: In this paper, a new structure of resonant metallic film based on bimetallic silver/gold layers (gold as an outer layer) is suggested, which combines advantages of both gold and silver resonant layers.

Resolution and sensitivity in surface plasmon microscopy and sensing

TL;DR: In this article, the use of surface plasmons on planar surfaces for the characterisation of those surfaces is analysed, and analytic expressions for the sensitivity of such characterisation to the variation of bulk refractive indices, and to the addition of thin dielectric layers on the plasmon supporting surface.

Surface plasmon microscopy

TL;DR: In this paper, surface plasmon microscopy methods are described which comprise irradiating a sample with a beam of electromagnetic radiation, wherein at least some of the radiation is incident on the sample at an angle or angles which results in the excitation of surface plasmons in the sample, and wherein the beam of radiation comprises a longitudinal axis passing through a focus of the beam.
