Abstract

A sandwich-type surface-enhanced Raman scattering (SERS) sensor using dual aptamers and gold-enhanced Raman signal probes has been successfully constructed for the detection of tumor-derived extracellular vesicles. The simple and sensitive sensor has the capability to detect tumor extracellular vesicles in 10-fold diluted human serum samples.
