Isolation of PD-L1 Extracellular Vesicle Subpopulations Using DNA Computation Mediated Microfluidic Tandem Separation

open access: yes, 2022
Accurate isolation of targeted extracellular vesicle (EV) is challenging due to the heterogeneity of EV subpopulations which are from different cell origins. Most EV subpopulations lack a single marker whose expression cleanly distinguish them from mixed
