Exosomes, molecular cargos secreted by almost all mammalian cells, are considered as promising biomarkers to identify many diseases including cancers. However, the small size of exosomes (30-200 nm) poses serious challenges in their isolation from complex media containing a variety extracellular vesicles (EVs) different sizes, especially sample volumes.

Exosomal microRNAs (miRNAs) are reliable and noninvasive biomarkers for the early diagnosis of cancer. Yet, accurate feasible detection exosomal miRNAs is often hampered by low abundance in exosomes requirement RNA extraction large sample volumes.
