Top Applications of Surface Plasmon Resonance Sensors (SPR Sensors): SPR sensors have revolutionized the field of chemical and biological sensing by providing real-time, label-free detection of molecular interactions with exceptional sensitivity. The working principle of an SPR sensor relies on the excitation of surface plasmons—coherent oscillations of free electrons—at the interface between a metal (typically […]
IntroductionTamm-plasmon-polaritons (TPPs) are optical surface states that arise at the interface between a metallic film and a photonic crystal (PC). Unlike traditional surface plasmon polaritons (SPPs), which require specific conditions for excitation (such as total internal reflection in a prism-coupled system), TPPs can be directly excited in normal incidence configurations, making them ideal for biosensing […]
Surface Plasmon Resonance (SPR) is a fundamental phenomenon in plasmonics that arises from the collective oscillations of conduction electrons at the interface between a metal and a dielectric. These oscillations are excited by incident electromagnetic waves under specific conditions, leading to enhanced electromagnetic fields and strong optical absorption. SPR is widely used in biosensing, nanophotonics, […]
