RNA-regulated molecular tweezers for sensitive fluorescent detection of microRNA from cancer cells.We describe here the construction of the DNA self-assembled molecular tweezers and the application of the tweezers for the monitoring of microRNA (miR-141) from human prostate cancer cells. 
RNA-regulated molecular tweezers
The self-assembly formation of the DNA tweezers and the regulation of the tweezers upon alternative addition of the fuel miR-141 and the anti-fuel strands are characterized by native polyacrylamide gel electrophoresis.
