Oscillating microbubbles sort exosomes from blood in minutes, skipping chemicals and centrifuges
Exosomes, secreted by most cells, carry biological information and proteins that serve as noninvasive biomarkers for diagnosing and predicting disease progression and metastasis. However, the rapid isolation of high-purity exosomes from various biofluids, such as undiluted whole blood, plasma and serum, remains a challenge.
