Integrated single-tube detection of miRNAs in subpopulation-specific extracellular vesicles via spatially colocalized dual-module DNA scaffold
A new single-tube test using CRISPR detects cancer-related molecules in blood more accurately by targeting specific cell-free particle types.
This in vitro study developed an integrated single-tube platform combining multivalent aptamer-based EV capture and CRISPR/Cas12a signal amplification on a modular DNA scaffold for subpopulation-specific EV miRNA detection, achieving low detection limits and demonstrating higher diagnostic AUC for cancer detection from MUC1+ compared to CD63+ EVs. The platform's modular design allows flexible reconfiguration for different EV subpopulations and miRNA targets, with potential application to non-invasive cancer diagnostics.
