Surface Plasmon Resonance (SPR) for the Evaluation of Shear-Force-Dependent Bacterial Adhesion [PDF]
Biosensors, 2015 The colonization of Escherichia coli (E. coli) to host cell surfaces is known to be a glycan-specific process that can be modulated by shear stress. In this work we investigate whether flow rate changes in microchannels integrated on surface plasmon resonance (SPR) surfaces would allow for investigating such processes in an easy and high-throughput ...

Surface Plasmon Resonance (SPR) as a Tool for Antibody Conjugate Analysis
Bioconjugate Chemistry, 1999Surface plasmon resonance (SPR) analysis was used to assess the immunoreactivity of anti-biotin (4) and anti-fluorescein (5) monoclonal antibody after conjugation with the N-hydroxysuccinimide ester of acridinium-9-carboxamide 1. Only minor changes in the apparent equilibrium dissociation constants of the antibody conjugates for their ligands resulted ...

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 ...

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.

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 ...

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.

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.

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)
