a Electrochemical detection of miRNA based on gold and silver nanorods and the reductive compound thionine. The overall structure is captured on the electrode’s surface via a nitrogen-doped reduced GO/AuNPs/tetrahedral DNA nanostructure. b An antibody-reduced GO for CTCs sensing. c A fluorescent biosensor based on fluorescence quenching/recovery by GO using fluorescent DNA probes and rolling circle amplification (RCA) triggered by miRNA target. GO graphene oxide, CTCs circulating tumor cells, AuNPs gold nanoparticles
