High‐throughput exosomes analysis for ovarian cancer screening based on a double‐positive surface marker detection biochip

open access: yesBMEMat, EarlyView.
A double‐positive surface marker detection approach was developed to conduct exosome surface protein detection in serum samples. It reaches single‐exosome detection, and over 300 exosome protein parameters are analyzed. The diagnostic accuracy achieved 90% in differentiation of high‐grade serous/serous ovarian carcinoma patients, benign patients, and ...
