Introduction Surface Plasmon Resonance Imaging (SPRi) has emerged as a vital optical sensing technique in the toolbox of modern biological research. Unlike conventional assays that depend on labeling or indirect detection, SPRi provides a label-free, real-time modality to monitor biomolecular interactions across multiple analytes simultaneously. This unique combination of high-throughput screening and non-destructive testing has […]
Introduction Surface plasmon-based sensing platforms have become indispensable tools in biosensing, pharmaceutical development, and environmental diagnostics. Among these, Surface Plasmon Resonance (SPR), Localized Surface Plasmon Resonance (LSPR), and Surface Plasmon Resonance Imaging (SPRi) represent the most widely applied technologies in the field of plasmonics. Each approach has distinct physical principles, detection strategies, and performance parameters […]
