Figure Lengend Snippet: Comparison of antibody-based and aptamer-based (aptasensor) methods for extracellular vesicle (EV) detection. The illustration highlights differences in recognition elements, sensor platform integration, signal readout methods, advantages, and limitations, where ptamer-based methods are more stable, easier to synthesize, and more adaptable, while antibody-based methods are established but less stable and harder to produce.
