Recent progress in electrochemical detection of tumor-derived exosomes

Abstract

Tumor-derived exosomes are tiny vesicles released from tumor cells to the extracellular environment. The sensitive and selective detection of tumor-derived exosomes is helpful for early diagnosis, clinical monitoring, curative effect evaluation and prognosis judgment of some tumors. In this paper, the detection of tumor-derived exosomes by electrochemical techniques are discussed, mainly including the direct, sandwich-like and magnetoelectric detection.
