Rapid and specific detection of copper chlorophyllin in food with turn-on fluorescence signal.

The rapid detection of copper chlorophyllin (Cu-Chl) is crucial for ensuring food safety. A key challenge in achieving specific detection is the effective elimination of interference from substances such as natural chlorophyll. Herein, a rapid fluorescence method for detecting Cu-Chl is developed. KMnO4 is employed to...

Specific cleavage of 5′ overhangs of non-target strand by Cas9 activated by target DNA binding

Abstract The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 system has become a powerful genome-editing tool that uses RNA–DNA pairing to cleave target DNA with protospacer adjacent motif (PAM) sequences. While its primary function is well-studied, secondary activities remain poorly understood,...
