Surface plasmon resonance (SPR) is a phenomenon occuring at metal surfaces (typically gold and silver) when an incident light beam strikes the surface at a particular angle.
In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the subject of intense research efforts. Plasmon physics is intriguing and its precise modelling proved to be challenging. In fact, plasmons are highly responsive to a multitude of factors, either intrinsic to the Au NPs or from the environment, and recently the need emerged for the correction of standard.
Abstract: Surface plasmon resonance (SPR) technology is widely used in biochemistry sensing, drug analysis, environmental monitoring and other fields. Based on the principle of surface plasmon resonance, high-precision SPR system was developed by using Kretschmann model in this paper. Automatic control, data acquisition, real-time display and.
Abstract: In this paper, we present a grating-coupled surface plasmon resonance (SPR) biosensor with a c-type fluidic channel on a grating disc. For obtaining the kinetic information of molecular interaction, we combined a c-type fluidic channel on disc to drive testing solution forward by gravity via turning the grating disc. The disc.
Surface Plasmon Resonance. Surface plasmon resonance (SPR) is a spectroscopic method which is used to detect protein interactions by immobilizing the ligand on a thin metal film and measuring the change in refractive index upon binding of the analyte.
Surface plasmon resonance (SPR) allows real-time, label-free detection of biomolecular interactions. SPR occurs when polarized light strikes an electrically conducting surface at the interface between two media. This generates electron charge density waves called plasmons, reducing the intensity of reflected light at a specific angle known as.
Plasmonics research has been a research focal point and has major impacts on many other scientific and technology fields, including sensors. In addition to conventional surface plasmon resonance sensing on metal thin films, a large variety of new physical-, chemical-, and biological-sensing systems are possible by introducing advanced plasmon resonance components or devices. Nowadays.
In this paper, a novel differential-phase-sensitive surface plasmon resonance biosensor (DP-SPRB) is proposed and developed, in which a two-frequency laser is integrated with a differential amplifier in order to analytically convert the phase modulation into amplitude modulation. With the use of the conventional envelope detection technique, the differential phase is precisely decoded in real.

Surface plasmon resonance (SPR) is one of the commonly used technologies for detailed and quantitative studies of protein-protein interactions and determination of their equilibrium and kinetic parameters. SPR provides excellent instrumentation for a label-free, real-time investigation of protein-protein interactions.
IV The interaction between miRNA with AuNR-ssDNA results in release of the AuNR-ssDNA from the antimonene nanosheets. The reduction in the molecular of the AuNR-ssDNA on the SPR surface makes for a significant decrease of the SPR angle. (1) Xue, T. et al.
