We describe a method for creating a mediator-containing interface between an enzyme and an electrode, achieving simpler and more reliable immobilization of the enzyme with the enhanced detection sensitivity. A nanothin polymer film containing a redox mediator, made of dimethylaminomethylferrocene, was plasma-deposited directly onto a glucose(More)
The structure and biosensor characteristics of complex between glucose oxidase (GOD) and plasma-polymerized nanothin film (PPF), in which the thickness is several nanometers, were investigated by atomic force microscopy (AFM) and electrochemical measurement. The GOD molecules were densely adsorbed onto the PPF surface treated by nitrogen plasma and the(More)
We propose an electron transfer-mediated amperometric enzyme biosensor based on plasma-polymerized thin film of dimethylaminomethylferrocene (DMAMF) on a sputtered gold electrode. The DMAMF plasma-polymerized film is deposited directly onto the surface of the electrode under dry conditions. The resulting thin film not only has redox sites but also is(More)
Adsorption of glucose oxidase (GOD) onto plasma-polymerized thin films (PPF) with nanoscale thickness was characterized by atomic force microscopy (AFM), quartz crystal microbalance (QCM), and electrochemical measurements. The PPF surface is very flat (less than 1-nm roughness), and its properties (charge and wettability) can be easily changed while(More)
