Abstract Electrochemically polymerized phenothiazines (thionine, methylene green, methylene blue, and toluidine blue) on carbon electrodes were investigated as electron transfer mediators of glucose oxidation by flavin adenine dinucleotide-dependent glucose dehydrogenase (FAD-GDH) for biosensor and biofuel cell applications. Among the tested polyphenothiazines grafted on a glassy carbon electrode, clear redox-mediating activity was observed for poly(methylene green), and the catalytic oxidation ...
Abstract Quartz crystal microbalance studies have been carried out to monitor the fusion of lipid vesicles (pure 1,2-dimyristoyl-sn-glycero-3-phosphocholine, DMPC) and mixed vesicles (DMPC and 4-decylaniline). In order to increase the stability of the lipid deposits onto the electrodes, we have developed an original approach involving electrografting of adsorbed mixed vesicles. Aryldiazonium salts generated in situ from 4-decylaniline (4DA) present in adsorbed and fused mixed vesicles at the ele...

Abstract The direct electrical connection of laccase on the electrode surface is a key feature in the design of efficient and stable biocathodes. However, laccase can perform a direct electron transfer only when it is in the preferred orientation toward the electrode. Here we report the investigation of the orientation of laccase from white rot fungus on multi-walled carbon nanotube surface modified with a naphthalene group. Naphthylated multi wall carbon nanotubes were synthesized and the kinet...

We designed a supported lipid bilayer (SLB) biomimetic membrane system that comprised polyaniline (PANI) to support a lipid bilayer membrane that incorporated Na+/H+ transporter proteins (NhaA) to give the system the capability of controllable electrogenic ion transport. The high turnover rate of NhaA (∼105 per min) provides the basis for this PANI-SLB-NhaA system to be a high-speed rechargeable biocapacitor that functions as a low-energy-consuming fast switch for biological engineering applicat...
We report a new approach to fabricate an efficient 3D glucose bioanode based on the co-immobilization of the enzyme glucose dehydrogenase (GDH), its cofactor NADP, and Multiwall Carbon Nanotubes (MWCNTs) coated with poly (methylene green) (PMG). The MWCNT-PMG composite was obtained by chemical polymerization of methylene green (MG) monomer on the MWCNT surfaces. Structural and chemical analyses clearly showed successful coating of the MWCNTs with PMG that markedly affected their morphological an...

Abstract We report enzymatic biofuel cells (EBFCs) based on MgO-templated carbon (MgOC)-carbon textile composite electrodes, which are lightweight, flexible, and used as liquid containers. MgOC particles with a pore size of 40 nm were modified on a carbon cloth substrate using poly(vinylidenedifluoride) as an anodic binder and polytetrafluoroethylene as a cathodic binder. Flavin adenine dinucleotide-dependent glucose dehydrogenase (FAD-GDH) from Aspergillus terreus was used for the anode, with 1...

Abstract There is a growing interest in the design and engineering of operational biofuel cells that can be implanted. This review highlights the recent progress in the electrochemistry of biofuel cell technologies, but with a particular emphasis on the medical and physiological aspects that impact the biocompatibility of biofuel cells operating inside a living body. We discuss the challenge of supplying power to implantable medical devices, with regard to the limitations of lithium battery tech...

Summary For practical outcomes, to avoid cumbersome and undesirable sample preparation, biosensors require engineered sample interfacing to control the dynamics of exchange at the sensing surface. This is a particular priority for biomedical biosensors, given the diversity of cellular and macromolecular sample constituents capable of disrupting not only the transduction sequence, but also of passivating the vulnerable sensing surface. Polymeric, and to a lesser extent inorganic membranes offer t...
