CATNAP (Cas trans -nuclease detection of amplified products), a method that integrates isothermal linear DNA amplification with Cas12a detection in a single reaction, bridges the sensitivity gap in CRISPR diagnostics while maintaining simplicity, making accurate disease detection more accessible in resource-limited settings.
Together, RTLC is successfully validated in practical samples by detecting lncRNA HULC and miR-21, offering a robust, versatile tool for high-performance nucleic acid diagnostics.
The design principles and working mechanisms of cascaded CRISPR strategies, encompassing Enzyme-Coupled cascades, Multi-effector class 2 CRISPR cascades, and Type III CRISPR-mediated cascades are introduced, including integration with digital detection platforms and AI-assistant algorithms are discussed.
