An ultrasensitive DNAzyme-based colorimetric DNA detection strategy was developed by utilizing gold nanoparticles modified with both peroxidase-mimicking DNAzymes and capture DNAs and magnetic nanoparticles modified with another capture DNAs, with a detection limit for a model Chlamydia gene of 50 fM.
基于 DNA zyme 的超灵敏比色 DNA 检测策略是通过利用同时修饰有过氧化物酶模拟 DNAzyme 和捕获 DNA 的金纳米颗粒以及另一个修饰有捕获 DNA 的磁性纳米颗粒来开发的，该策略对模型衣原体基因的检测限为 50 fM。
