Introduction Fiber-optic Surface Plasmon Resonance (SPR) sensors represent a pivotal advancement in optical sensing technologies. These sensors combine the extraordinary sensitivity of SPR with the versatility and portability of fiber-optics, offering a powerful platform for field-deployable bio/chemical detection. Particularly valuable in environmental monitoring, pathogen detection, and real-time diagnostics, fiber-optic SPR sensors have seen a surge […]
Introduction The confluence of microfluidic technology and surface plasmon resonance (SPR) sensing represents a pivotal advancement in the evolution of miniaturized analytical systems. Historically, SPR sensors—while extremely sensitive to refractive index changes at the nanoscale—have been encumbered by operational limitations. These include reliance on manual sample delivery, low multiplexing throughput, and often bulky system architecture. […]
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, […]
