We report on a novel graphene-based nanoarchitecture modified with plasma-polymerized propargylamine (G-PpPG) and its application in electrochemical sensors for DNA. Films of G-PpPG were characterized by X-ray photoelectron spectroscopy and electrochemical impedance spectroscopy. The presence of graphene enhances the electrochemical activity of the films, and the high density of amino groups (deposited...
We report on a novel nanoarchitecture for use in highly bioactive electrochemical biosensors. It consists of multilayers of nanostructured plasma-polymerized pyrrole (ppPY) and nanosheets of electrically conductive graphene. The ppPY films were deposited by plasma-enhanced chemical vapor deposition on a graphene surface to form nanostructured composites (G-ppPY). The G-ppPY films were then coated...
