Based on target-triggered dynamic hairpin assembly (DHA) in both unidirectional and bilateral growth manners DNA nanobrushes are constructed, which realize sensitive and selective detection of short miRNA (miR-21) and long DNA (BRCA1), respectively. Moreover, the unidirectional DHA strategy is readily applied to in situ imaging of miR-21 in different live cells.
基于在单向和双向生长方式下的靶触发动态发夹组装（DHA），构建了 DNA 纳米刷，分别实现了对短 miRNA（miR-21）和长 DNA（BRCA1）的灵敏和选择性检测。此外，还将单向 DHA 策略应用于不同活细胞中 miR-21 的原位成像。
