Paper-based devices chemically functionalized with capturing molecules enable the isolation and characterization of extracellular vesicles (EVs) from samples of limited amount. Here, we describe the isolation of EV subpopulations from human serum samples. The morphology, content, and amount of captured EVs can be assessed using scanning electron microscopy (SEM ), transcriptome analysis, and paper-based enzyme-linked immunosorbent assays (pELISA), respectively. A colorimetric readout can be detected from 10 μL serum within 10 min.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
