A sensitive and visual colorimetric biosensor for liver cancer-associated miRNA using Exo-III assisted target recycling and a cyclization-functional DNAzyme walker.
The accurate detection of liver cancer-associated microRNAs (miRNAs) remains challenging due to their low abundance and high sequence homology. Herein, we report a colorimetric biosensor integrating Exo-III-assisted target recycling with a cyclization-functional DNAzyme walker for sensitive and highly specific miRNA de...
