A G-quadruplex-assisted target-responsive dual-mode aptasensor based on copper nanoclusters synthesized in situ in a DNA hydrogel for ultrasensitive detection of ochratoxin A

Developing ultrasensitive sensing platforms for trace ochratoxin A (OTA) in food safety is still challenging. Herein, we presented a novel dual-mode sensing strategy for fluorescence and colorimetric detection of OTA by combining the target-responsive hemin-encapsulated and copper nanoclusters (CuNC...
