Abstract

We report a highly sensitive and specific nanobiosensor for the detection of tumor-derived extracellular vesicles (tdEVs) with a limit of detection of 10 tdEVs/μL. After selective capture on surface modified electrodes, we use a combination of an enzymatic sandwich assay and redox cycling between nanointerdigitated electrodes (nIDEs).
