title: A difunctional DNA-AuNP dendrimer coupling DNAzyme with intercalators for femtomolar detection of nucleic acids.
abstract: A novel difunctional DNA-nanogold (AuNP) dendrimer with a hemin-G-quadruplex was for the first time utilized as the nanotag for the in situ amplified electronic signal for nucleic acid detection by coupling high-efficiency DNAzyme with the intercalated methylene blue (MB).
