“…30 to 100 mW cm À2 , respectively). The power density of the here presented Reactor 3 can be compared to other glucose/oxygen fuel cells based on GOx and BOD or laccase as cathode [39][40][41][42][43][44]. The performance of our reactor is superior compared to the enzymatic fuel cell with the same combination of enzymes and a maximum power density of around 5 mW cm À2 for 20 mM glucose solution [36].…”

A B S T R A C TGlucose was selectively oxidized to gluconic acid in a membraneless, flow-through electroenzymatic reactor operated in the mode of co-generating chemicals and electrical energy. At the anode the enzyme glucose oxidase (GOx) in combination with the redox mediator tetrathiafulvalene (TTF) was used as catalyst, while the cathode was equipped with an enzyme cascade consisting of GOx and horseradish peroxidase (HRP). The influence of the electrode preparation procedure, the structural and the operating parameters on the reactor performance was investigated in detail. Under optimized conditions, an open circuit potential of 0.75 V, a current density of 0.6 mA cm À2 and a power density of 100 mA cm À2 were measured. The space time yield of gluconic acid achieved at a glucose conversion of 47% was 18.2 g h À1 cm À2 .

“…This bioanode satisfactorily exceeds the performance of recent MWNTs-based designs. 40 The bioanode was redesigned to a reagentless NAD + -dependent GDH anode. The NAD + -cofactor was tethered to the surface of the MWNTs-wall by employing a linker capable of adsorbing on the CNT-wall by π-π stacking interaction from the pyrenyl end of the molecule.…”

Reagentless and non-reagentless nicotinamide adenine dinucleotide (NAD + )-dependent glucose dehydrogenase (GDH) bioanodes integrating multiwalled nanotubes (WMNTs)-bucky papers are introduced in this study. The NAD + was tethered by pyrene butanoic acid succinimidyl ester (PBSE) to the wall of the carbonic MWNTs composing the bucky paper by π-π stacking interactions. The designs have been evaluated electrochemically and by X-ray spectroscopy. The electrodes have been assembled to a quasi-2D microfluidic system with capillary driven flow. Michaelis-Menten analysis on CMN-MG-PBSE-NAD + -GDH, reagentless bioanode, in an electrolytic cell shows a limiting current and constant of I Max = 3.252 ± 0.134 mA.cm −2 and K M = 48.3 ± 4.6 mM at 4 • C, and I Max = 2.568 ± 0.085 mA.cm −2 and K M = 13.6 ± 1.8 mM at 25 • C for 0.1 M glucose. Results demonstrate the enzymatic system, in non-reagentless and reagentless bioanode, has an extraordinary current density generation. In the reagentless bioanode design, the enzyme and its cofactor are highly catalytically active, and the design can be feasible integrated into biofuel cell assembly and later used as a power source for small portable devices. The development and implementation of alternative energy systems is highly desired and envisioned for overcoming environmental issues. Furthermore, designing environmentally friendly power devices is needed because current systems such as conventional batteries have shown to contain toxic compounds and produce toxic residues. 1Harvesting energy from glucose, for example, would make possible the utilization of fruits as well as commercial drinks as source of biofuel and the products of their oxidation are naturally biodegradable. Enzymatic biofuel cells are devices engineered for that purpose. 2-4These biofuel cells are envisioned to power small portable devices and devices for biomedical applications. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Increasing the efficiency of the biofuel cell systems requires decreasing limitations on the kinetics of the catalytic layer, resistivity losses of the electrode materials and mass transport losses. In previous work, we reported the integration of bucky papers 18 (multiwalled carbon nanotube (MWNTs)-based papers) to bioelectrode designs to reduce kinetic and ohmic limitations. The employment of a quasi-2D microfluidic system (paper-based fan) was employed to decrease mass transport limitations of fuel to the catalytic layer. The enzymatic systems were immobilized within CNTs network-Chitosan 3D-matrix in order to improve electron transfer and enzyme life-time. Herein, the improvement of the NAD + -dependent glucose dehydrogenase (GDH)-based bioanode is presented.Harvesting energy from glucose by enzymatic biofuel cells could be performed by using oxidoreductase enzymes such as glucose dehydrogenase (GDH) on the anode 19 and analogous enzymatic systems on the cathode for reduction of oxygen from air. 20,21 At the anode, GDH shows a biocatalytic activity when coupled to its NAD + /NADH-...
