Abstract
Systems and techniques are described for capturing target extracellular vesicles from a fluid sample. In some implementations, a microfluidic device includes a microfluidic channel where an internal surface of at least one wall of the microfluidic channel includes a plurality of grooves or ridges, or both grooves and ridges, arranged and configured to generate chaotic mixing within a fluid sample flowing through the microfluidic channel. The microfluidic device also includes a plurality of elongate flexible linker molecules, each having a molecular weight between about 1.8-4.8 kDa, where each elongate flexible linker molecule is bound at a first end to an internal surface of at least one wall of the microfluidic channel and is bound at a second end to one or more binding moieties that specifically bind to a target extracellular vesicle.
