Photons of p-polarized light can interact with the free electrons of the metal layer; inducing a wave-like oscillation of the free electrons, thereby reducing the reflected light intensity. One of such techniques is surface plasmon resonance (SPR) spectroscopy, a label-free technique which enables measurement of real-time ligand-binding affinities and kinetics using relatively small amounts of membrane protein in a native or native-like environment (Olaru et al., 2015). 1996-05-21 · The measured binding affinity of cholera toxin for the ganglioside sequence ranges from 4.61 × 10-12 M for GM1 to 1.88 × 10-10 M for asialo GM1. The picomolar values obtained by surface plasmon resonance are similar to K d values determined with whole-cell binding assays. 2017-05-22 · Surface Plasmon Resonance (SPR) is a widely used label-free detection technique for studying binding behavior of biomolecules. Since its commercialization in 1990’s, SPR has made vast advances in terms of both development of the technology and its applications.

From small molecules to large proteins, or even viruses, the technique has a number of applications in the Biopharmaceutical industry, which include, but are not limited to: Therefore, a high-resolution glucose detection method is required for detecting glucose concentration in diluted ISF. In this paper, an optical surface plasmon resonance (SPR) sensor modified by the glucose/galactose-binding (GGB) protein which has good affinity to glucose molecules was presented for specific and sensitive glucose detection.
