The detection of cancer in its early stages can greatly prevent disease development, however, current technologies for tumor detection present several limitations. Here, the authors develop a paper-based electrochemical device for detecting cancer-derived small extracellular vesicles (S-EVs) in fluids, recognizing αvβ6-containing S-EVs down to a limit of 0.7*103 S-EVs/mL with a linear range up to 105 S-EVs/mL.
