Illustration of the scale of extracellular vesicles and microfluidics compared to other biological components. This schematic provides a scale range from 1 angstrom (Å) to 1 mm (mm), mapping out the typical diameters of various biological entities in comparison to extracellular vesicles (EVs) and acoustic trapping components (seed particles and the trapping capillary) pertinent to our research.
