Enzyme inhibition-enabled CRISPR/Cas12a biosensing system for heparin-related non-nucleic acid biomarkers

In contrast to conventional CRISPR/Cas12a systems, which rely on complex functional nucleic acids, protein switches, or allosteric transcription factor (aTF)-based signal conversion for non-nucleic acid analysis, this work achieves more facile quantification of non-nucleic acid biomarkers through a novel heparin-mediated Cas12a inhibition mechanism.
