Surface plasmon resonance sensors for detection of chemical and biological species.

Since the first application of the surface plasmon resonance (SPR) phenomenon for sensing almost two decades ago, this method has made great strides both in terms of instrumentation development and applications. SPR sensor technology has been…

In this paper, the authors are interested in the detection of biol. mols. This detection relies on the use of nanosensors based on localized surface-plasmon resonance (LSPR). The authors discuss the sensitivity of these nanosensors by studying the…

This paper addresses the optimization of prism-coupled, wavelength-interrogated surface-plasmon resonance (SPR) sensors. Limit of detection (LOD), rather than sensitivity, is chosen as a figure of merit. The Cramer-Rao bound (CRB) for spectral shift…

We report the achievement of sensitive chemical and biological sensing using periodic gold nanopyramids with nanoscale sharp tips created by a simple and scalable colloidal templating approach. The sharp tips and the long-range periodic structure of…

Planar waveguide surface plasmon resonance sensors have great potential for use in the field of environmental monitoring. In this paper we present a rigorous model for the optical power transmittance of this type of sensor. This model is used to…

We report a sensor consisting of two micromachined cantilevers (a sensing/reference pair) that is suitable for detection of chemical and biological species. The sensing strategy involves coating the sensing cantilever with receptors that have high…

ARROW-B surface plasmon resonance sensors operating in aqueous environment for biomolecular interaction analysis are investigated. The detectable changes of the refractive index down to the order of 10∼5 can be achieved.

A fiber optic imaging sensor is presented that utilizes surface plasmon resonance (SPR) excitation. The configuration of this sensor allows for remote sensing and multiplexing. The sensor is advantageous in that it eliminates the traditional bulk…

Theoretical analysis of the sensitivity of surface plasmon resonance (SPR) sensors with spectral interrogation is presented. Two basic configurations of SPR sensors with spectral interrogation are investigated-for the measurement of variations in…

Surface plasmon resonance (SPR) scanning and imaging measurements have many applications in chemical and biological sensing. In this paper, we have used SPR to study protein adsorption onto chemically modified gold surfaces. We present a method for…
