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 Resonance Imaging (SPRI) has emerged as a pivotal label-free optical technique that enables real-time observation of biomolecular interactions and cellular dynamics. Unlike conventional fluorescence-based assays, SPRI relies on monitoring changes in the refractive index at a metal-dielectric interface—typically involving gold films—making it highly sensitive to surface-bound molecular events. This unique capability allows […]
