Abstract
Extracellular vesicles (EVs) have emerged as valuable sources for liquid biopsy in disease diagnostics, given their protein and nucleic acid cargoes (e.g., miRNA, mRNA, glycoRNA) can serve as critical biomarkers. DNA nanotechnology, leveraging its inherent programmability, high specificity, and powerful signal amplification capability, offers a transformative approach for the bioanalysis of EVs. This review summarizes recent advances in DNA nanotechnology-based analytical methodologies for detecting EV-associated proteins and nucleic acids. We detail the underlying principles, applications, and performance of key strategies, including aptamer-based recognition, enzyme-free catalytic amplification circuits (e.g., HCR, CHA), enzyme catalytic amplification techniques (e.g., RCA, CRISPR-Cas systems), and DNA nanostructures-assisted amplification. The integration of these DNA tools into multiplexed detection platforms is also discussed. Finally, current challenges and future perspectives concerning clinical translation of EV detection are presented.
期刊介绍：
Nanoscale Horizons stands out as a premier journal for publishing exceptionally high-quality and innovative nanoscience and nanotechnology. The emphasis lies on original research that introduces a new concept or a novel perspective (a conceptual advance), prioritizing this over reporting technological improvements. Nevertheless, outstanding articles showcasing truly groundbreaking developments, including record-breaking performance, may also find a place in the journal. Published work must be of substantial general interest to our broad and diverse readership across the nanoscience and nanotechnology community.
