A boosting upconversion luminescent resonance energy transfer and biomimetic periodic chip integrated CRISPR/Cas12a biosensor for functional DNA regulated transduction of non-nucleic acid targets.
除基因编辑外,CRISPR/Cas系统因靶标识别准确度高而成为生物传感领域的新选择,但现有传感器多限于核酸分析,且在复杂样品中适应性差、灵敏度不足。本文提出若干新策略突破瓶颈:首先,通过设计适配体(用于蛋白质)和DNAzyme(用于金属离子)等功能DNA,将非核酸靶标的识别事件转导为CRISPR/Cas12a反式切割的激活;其次,利...
