Abstract:
Highly sensitive and reliable PEC detection of miRNAs still faces some challenges like the inaccuracy caused by coexisting interferences in the PEC system. Herein, we developed a split-type "turn-off" PEC biosensor based on spatially-extended 3D magnetic DNA nanodevices with high-order DNA amplifiers for sensitive detection of miRNAs in cancer cells.
