“…The size of the NPs can be tuned during the synthesis, being in the range of a few nanometers to hundreds of nanometers. [209,210] Contrary to many former studies, a recent work has shown, however, that the efficiency of the catalytic reduction of O 2 by BOD does not depend on the diameter of the NPs, [211] highlighting that the mechanism regarding such materials needs to be examined in depth. It is most probably strongly dependent on the method by which the NPs are deposited.…”

“…Generally, the direct catalytic current is increased due to a concomitant effect of an increase in the surface area and a potential electron hopping between the NP and the electrical relay on the enzyme surface. [210,212,213] As an example, a 30-fold increase of the surface area was shown by successive layers of Au NPs. [174] More sophisticated architectures can be designed by covalent attachment of Au NPs on graphite, before enzyme covalent attachment.…”

Biohydrogen for a New Generation of H₂/O₂ Biofuel Cells: A Sustainable Energy Perspective

et al. 2014

Among sustainable alternatives to fossil fuel, proton exchange membrane fuel cells are promising devices that deliver electricity from hydrogen and oxygen, producing only water. The transformation of the fuel and oxidant however relies on rare‐metal catalysts. H2/O2 enzymatic biofuel cells thus emerge as sustainable biotechnological devices in which chemical catalysts are replaced by hydrogenases at the anode and multicopper oxidases at the cathode. This review discusses the recent breakthroughs and the limitations in all the components of H2/O2 biofuel cells: 1) Catalytic mechanisms involved in multicopper oxidases and hydrogenases, in addition to the new potential of enzymes from the biodiversity pool, which exhibit outstanding properties. 2) The molecular basis for oriented enzyme immobilization on the electrochemical interfaces as a prerequisite for a fast direct electron‐transfer rate. 3) The requirement for 3D networks to enhance current densities. 4) The production of H2 from biomass. 5) The history of H2/O2 biofuel cells and recent devices, which also highlights the remaining issues that will allow the use of such devices in low‐power applications.

“…In comparison, a 50% loss in response for a glucose/H 2 O 2 biofuel cell with glucose oxidase reconstituted onto a pyrroloquinoline quinine and FAD (PQQ-FAD) monolayer at the anode and microperoxidase-11 at the cathode was observed over a period of 180 min [43]. A stable glucose/O 2 DET based biofuel cell with a CDH and BOD modified gold bioanode and biocathode, respectively, maintained 90% of the original response after a 5-hour measurement period and lost only 20% of its response after 12 hours of constant operation [27].…”

“…A glucose/O 2 multi-stacked biofuel cell generating a power output of 1.25 mW/mL, sufficient to power a radio-controlled car of mass 16.5 g has been described [26]. The power density of a mediatorless glucose/O 2 gold nanoparticle-based biofuel cell operating for 12 hours in physiological buffer decreased by 20% over a period of 12 hours [27]. A glucose/O 2 biofuel cell implanted in a grape displayed a power output of 0.47 Wmm -2 which decreased by 22% after 24 hours of continuous operation [15].…”

Abstract:Nanoporous and planar gold electrodes were utilised as supports for the redox enzymes Aspergillus niger glucose oxidase (GOx) and Corynascus thermophilus cellobiose dehydrogenase (CtCDH). Electrodes modified with hydrogels containing enzyme, Os-redox polymers and the cross-linking agent poly(ethylene glycol)diglycidyl ether (PEGDGE) were used as biosensors for the determination of glucose and lactose. Limits of detection of 6.0 (± 0.4), 16.0 (± 0.1) and 2.0 (± 0.1) µM were obtained for CtCDH modified lactose and glucose biosensors and GOx modified glucose biosensors, respectively, at nanoporous gold electrodes. Biofuel cells comprised of GOx and CtCDH modified gold electrodes were utilised as anodes, together with Myrothecium verrucaria bilirubin oxidase (MvBOD) or Melanocarpus albomyces laccase (rMaLc) as cathodes, in biofuel cells. A maximum power density of 41 µW/cm 2 was obtained for a CtCDH/MvBOD biofuel cell in 5 mM lactose and O 2 saturated buffer (pH 7.4, 0.1 M phosphate, 150 mM NaCl).2

Miniature Direct Electron Transfer Based Enzymatic Fuel Cell Operating in Human Sweat and Saliva

View full text Add to dashboard Cite

We present data on operation of a miniature membrane‐less, direct electron transfer based enzymatic fuel cell in human sweat and saliva. The enzymatic fuel cell was fabricated following our previous reports on miniature biofuel cells, utilizing gold nanoparticle modified gold microwires with immobilized cellobiose dehydrogenase and bilirubin oxidase. The following average characteristics of miniature glucose/oxygen biodevices operating in human sweat and saliva, respectively, were registered: 580 and 560 mV open‐circuit voltage, 0.26 and 0.1 μW cm–2 power density at a cell voltage of 0.5 V, with up to ten times higher power output at 0.2 V. When saliva collected after meal ingestion was used, roughly a two‐fold increase in power output was obtained, with a further two‐fold increase by addition of 500 μM glucose. Likewise, the power generated in sweat at 0.5 V increased two‐fold by addition of 500 μM glucose.
