Detection limits of confocal surface plasmon microscopy

Confocal surface plasmon microscopy with pupil function engineering.

Surface Plasmon microscopy can measure local changes of refractive index on the micron scale. Interferometric plasmon imaging delivers quantitative high spatial resolution sensitive to refractive index. In addition the so called V(z) method allows image contrast to be controlled by varying the sample defocus without substantially degrading spatial resolution. Here, we show how a confocal system...

Transmission surface plasmon resonance microscopy

Confocal microscopy with an increased detection aperture: type-B 4Pi confocal microscopy.

We show the point-spread function of a confocal microscope with an increased detection aperture. The increase in aperture is accomplished by coherent collection of the light from the specimen with two opposing objective lenses, i.e., type-B 4Pi confocal microscopy. We demonstrate experimentally its feasibility for detecting scattered or fluorescently emitted light. The 4Pi confocal point-spread...

Surface Plasmon Spectroscopic Detection of Saxitoxin

For the surface-optoelectronic study of Saxitoxin sensing, we fabricated selfassembled calix[4]arene derivative monolayers as the recognition-functional interfaces on a gold surface. An interaction study between Saxitoxin and calix[4]arene derivative monolayers were performed using surface plasmon resonance (SPR) spectroscopy. Among three calix[4]arene derivatives, calix[4]arene crown ether SAM...

Detection of Salmonella by Surface Plasmon Resonance

This study explores the possibility of simultaneous and specific detection of Salmonella serovars by surface plasmon resonance (SPR). The Plasmonic SPR device was used to develop this rapid assay. The sandwich immunoassay involves the use of a polyclonal anti-Salmonella antibody to simultaneous capture multiple Salmonella serovars present in a sample. This is followed by specific detection of t...
