High power enzymatic biofuel cell based on naphthoquinone-mediated oxidation of glucose by glucose oxidase in a carbon nanotube 3D matrix.
A novel glucose/O2 biofuel cell (GBFC) integrating carbon nanotube-based 3D bioelectrodes and using naphthoquinone-mediated oxidation of glucose by glucose oxidase and direct oxygen reduction by laccase is reported, showing among the best in vitro performances for a GBFC.
Supercapacitor/biofuel cell hybrids based on wired enzymes on carbon nanotube matrices: autonomous reloading after high power pulses in neutral buffered glucose solutions
We report an original setup using carbon nanotube matrices as supercapacitors where redox enzymes serve for continuous charging of the capacitors. High currents can be delivered under short pulse
Impedimetric biosensor for cancer cell detection
Abstract Electrochemical impedance spectroscopy was evaluated for the label free detection of MCF-7 cancer cell in which c-erbB-2 receptor is overexpressed on the cell surfaces. Anti-c-erbB-2, used
Electrocatalytic oxidation of glucose by rhodium porphyrin-functionalized MWCNT electrodes: application to a fully molecular catalyst-based glucose/O2 fuel cell.
The M WCNT/(DPDE)Rh(III) electrode was finally integrated in a novel design of an alkaline glucose/O(2) fuel cell with a MWCNT/phthalocyanin cobalt(II) (CoPc) electrode for the oxygen reduction reaction.
Efficient direct oxygen reduction by laccases attached and oriented on pyrene-functionalized polypyrrole/carbon nanotube electrodes.
A "pseudo" host-guest interaction of polymerized pyrene with a hydrophobic cavity of laccase was used for the oriented enzyme immobilization on MWCNT electrodes, which leads to higher catalytic current for oxygen reduction and higher electroenzymatic stability.
Freestanding HRP–GOx redox buckypaper as an oxygen-reducing biocathode for biofuel cell applications
Horseradish peroxidase (HRP) was immobilized on redox buckypapers followed by electropolymerization of pyrrole-modified concanavalin A enabling the subsequent additional immobilization of the
Supramolecular immobilization of laccase on carbon nanotube electrodes functionalized with (methylpyrenylaminomethyl)anthraquinone for direct electron reduction of oxygen.
The resulting bioelectrodes show excellent stability over weeks and can thus be envisioned in enzymatic biofuel cells and could be doubled simply by using the bis-anthraquinone compound.
Glucose fuel cell based on carbon nanotube-supported pyrene–metalloporphyrin catalysts
It is important to design a functionalization scheme for carbon nanotubes that preserves their outstanding proprieties, while adding new proprieties, thereby enabling their integration in fuel cell
A synthetic redox biofilm made from metalloprotein-prion domain chimera nanowires.
The design of a protein-only redox film inspired by the architecture of bacterial electroactive biofilms is reported, and it is demonstrated that bionanowires can be used as electron-transfer mediators to build a bioelectrode for the electrocatalytic oxygen reduction by laccase.
