Surface plasmon resonance (SPR) as a rapid tool for serotyping of Salmonella
Biosensors and Bioelectronics, 2010An SPR-based sandwich immunoassay for serotyping of Salmonella is demonstrated. The Salmonella are captured on an SPR chip using polyclonal capture antibody. SPR sensorgrams are obtained for the immunoreactions of the somatic (O) and flagellar (H) surface antigens, of the captured bacteria, to their respective antibodies.

Rapid and Label-Free Bacteria Detection by Surface Plasmon Resonance (SPR) Biosensors
Biotechnology Journal, 2009AbstractSurface Plasmon Resonance (SPR) biosensor technology has been successfully used for the detection of various analytes such as proteins, drugs, DNA, and microorganisms. SPR‐based immunosensors that coupled with a specific antigen‐antibody reaction, have become a promising tool for the quantification of bacteria as it offers sensitive, specific ...

Surface plasmon resonance (SPR) spectra of different saccharides were collected using a home-made multiwavelength SPR apparatus. Pentoses, hexoses, disaccharides and a trisaccharide were distinguished from one another according to their SPR spectra collected at the same concentration.

Evaluation of Surface Plasmon Resonance (SPR) for Heparin Assay
Journal of Colloid and Interface Science, 1997The concentration of heparin, an anticoagulant in blood, is usually inferred from clotting type assay, which determines a parameter related to the heparin activity. Because of the heterogeneity of heparin, however, it is desirable to monitor the absolute concentration of heparin directly in the clinical range of 0-2 U/ml. Surface plasmon resonance (SPR)

Sensitivity comparison of surface plasmon resonance (SPR) and magneto-optic SPR biosensors
The European Physical Journal Plus, 2019Sensitivity of a biosensor is one of the most important parameters that determines its performance. It depends on many factors, such as excitation wavelength of incident optical radiation (\( \lambda\) , composition, type, and thickness of the ferromagnetic Co layer ( \( t_{\rm Co}\) , plasmonic Au, and high refractory metal, Ti, involved, and sensing ...

Electrochemical surface plasmon resonance (EC-SPR) aptasensor for ampicillin detection
Analytical and Bioanalytical Chemistry, 2019Surface plasmon resonance technique is highly sensitive to various processes taking place on a metal film and it has emerged as a powerful label-free method to study molecular binding processes taking place on a surface. Another important but less explored area of applications is the use of hybrid methods which combine electrochemistry with optical ...

Supramolecular surface plasmon resonance (SPR) sensors for organophosphorus vapor detection
Journal of Materials Chemistry, 2007We synthesized cavitands containing COOH moieties at the upper rim of the cavity and evaluated the interaction between these cavitands and the sarin nerve gas simulant, dimethylmethylphosphonate (DMMP) using surface plasmon resonance (SPR) spectroscopy.

Detection of Serum Antibodies to S‐Antigen by Surface Plasmon Resonance (SPR)
Journal of Immunoassay and Immunochemistry, 2006Serum autoantibodies to visual arrestin, also termed S-antigen, have been shown to accompany several autoimmune-related diseases. However, they were also detected in sera of healthy individuals; there is lack of a sensitive and fast method for evaluation of putative differences between those two groups of antibodies.

Thermal desorption investigations on self-assembled monolayers (SAMs) had previously been carried out using techniques such as thermal desorption spectroscopy (TDS), scanning tunneling microscopy (STM) and X-ray photo-electron spectroscopy (XPS). In this paper, the thermal dissociation of alkanethiols (CnH2n+1SH) at various chain lengths (n = 6, 12, 18)
