Abstract
Surface plasmon resonance (SPR ) enables real-time, label-free detection of ligand binding to target receptors immobilized on a sensing surface. SPR has emerged as a promising technique for extracellular vesicle (EV) characterization with its label-free detection scheme, and exquisite sensitivity. Among the various system configurations, nanohole-based SPR sensors are of particular interest because of their simple optical setup, tunability, and scalability. Here, we describe the characterization of circulating EVs or exosomes from human clinical samples using a nanohole-based SPR sensor, named nPLEX (nano-plasmonic exosome) sensing.
