A Smart DNA Network-Based Diagnostic System for Enrichment and Detection of Circulating Tumor Cells in Cancer Liquid Biopsy

Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Апрель 4, 2025

Circulating tumor cells (CTCs) have emerged as critical biomarkers in liquid biopsy for noninvasive diagnosis and real-time monitoring of cancer progression. However, the isolation CTCs is often required before detection due to their ultralow abundance peripheral blood. These processes are typically time-consuming prone cell loss, which limits utility CTC-based biopsy. Herein, we present a DNA network-based diagnostic system that enables specific recognition, selective enrichment, accurate directly from blood samples. The network comprises ultralong chains embedded with polyvalent aptamers fluorescence modules. selectively bind epithelial adhesion molecule (EpCAM) on CTC membrane, facilitating enrichment through base pairing-driven formation. This semiquantitatively detects expression level cancer-associated microRNA within using ratiometric imaging based chemical assembly two In clinical samples, this achieves 100% precision 96% accuracy distinguishing breast patients healthy donors, highlighting its promising potential diagnosis.
