DNA enzyme-decorated DNA nanoladders as enhancer for peptide cleavage-based electrochemical biosensor

DNA enzyme-decorated DNA nanoladders as enhancer for peptide cleavage-based electrochemical biosensor

BB Kou, L Zhang, H Xie, D Wang, YL Yuan… - … applied materials & …, 2016 - ACS Publications

Herein, we developed a label-free electrochemical biosensor for sensitive detection of
matrix metalloproteinase-7 (MMP-7) based on DNA enzyme-decorated DNA nanoladders as
enhancer. A peptide and single-stranded DNA S1-modified platinum nanoparticles (P1 …
