Core-shell Gold Silver Nanoparticles for LSPR-Based Naked

The SPR method is based on optical measurement of refractive index changes associated with the binding of analyte molecules in a sample to biorecognize molecules immobilized on the SPR sensor. Surface Plasmon Resonance - BiaCore Biosensor SPR is a universal tool for studying and characterizing macromolecular interaction in a label-free state. The system detects the binding reaction in real time by monitoring changes in mass concentration at the chip surface; the association and dissociation rate constants are determined directly from Surface plasmon resonance (SPR)-based biosensors are very powerful tools for the study of biomolecular interactions, chemical detection and immunoassays. This paper reviews the performance of various SPR structures and detection schemes focusing on propagating surface plasmons generated in planar structures. This review aims to highlight the applications of one of the most prominent optical biosensor technologies, surface plasmon resonance (SPR), in the drug discovery process and quality analysis of pharmaceutical compounds and their particularities.

Surface plasmon resonance (SPR) based sensors are used in biochemistry and biology to detect the molecular concentration, thickness and specific chemical analytes. Surface plasmons are the quanta of surface charge density oscillation [ 2 ] likewise the collective oscillations in electron density at surface of metal whose propagation is confined to metal dielectric interface. Here we present a novel surface plasmon resonance (SPR) biosensor for the rapid and quantitative detection of PAPP-A2 in blood samples. This biosensor uses a single surface referencing approach and a sandwich assay with functionalized gold nanoparticles for signal enhancement.
