We developed a novel biosensor electrode for nitrite ions. Gold dendritic nanostructures (Au-DNs) are directly electrochemically co-deposited from 4E peptides engineered M13 virus (M134E) mixed electrolyte on to the ITO electrode. The M134E could specifically nucleate Au precursor, which enable the efficient growth of dendritic nanostructures, whereas such structures were not obtained in the presence of wild-type M13 virus. The structural features of the Au-DNs and their interfacing mechanism with ITO electrode are characterized by SEM, EDX and XRD analysis. The growth mechanism of Au-DNs at ITO electrode has been elucidated by SEM measurements. The M134E induces the formation and plays a crucial role in shaping the dendrite morphology of Au nanostructures. Biosensor electrode constructed using Au-DNs modified electrode for nitrite ions and found improved sensitivity relative to the sensor electrode prepared from wild-type M13, Y3E peptides engineered M13 and without M13. Our novel biosensor fabrication can be extended to other metal and metal oxides and its application might be useful to develop novel biosensor for variety of biomolecules.
