Orthogonal DNA barcoding enables subpopulation-resolved extracellular vesicle miRNA profiling
Extracellular vesicle–associated microRNAs (EV-miRNAs) hold promise for liquid biopsy, but their clinical utility is hindered by EV heterogeneity. Here, we report DEEPER, a DNA-encoded orthogonal recognition platform for selective barcoding of tumor-derived EV subpopulations and in situ miRNA profiling. DEEPER uses fou...
