“…Peaks in the voltage-current curves would be observed at potentials corresponding to the potentials of the enzyme active centers, such as PQQ and T1 in GDH (Katz et al, 1999) and laccase (Calabrese Barton et al, 2004), respectively, in order to confirm the direct electrochemistry between the enzyme active center and electrode surface.…”

“…In order to perform potentially favorable biofuel cell operation based on glucose oxidation and oxygen reduction at the anode and cathode electrodes, respectively, oxygen-reducing laccase was selected for the cathodic reaction. Laccase is a well-known biocatalyst that is commonly used in EBFCs (Calabrese Barton et al, 2004), and it is compatible with the buckypaper electrode (Hussein et al, 2011).…”

The requirement for a miniature, high density, long life, and rechargeable power source is common to a vast majority of microsystems, including the implantable devices for medical applications. A model biofuel cell system operating in human serum has been studied for future applications of biomedical and implantable medical devices. Anodic and cathodic electrodes were made of carbon nanotube-buckypaper modified with PQQ-dependent glucose dehydrogenase and laccase, respectively. Modified electrodes were characterized electrochemically and assembled in a biofuel cell setup. Power density of 16.12 μW cm −2 was achieved in human serum for lower than physiological glucose concentrations. Increasing the glucose concentration and biofuel cell temperature caused an increase in power output leading up to 49.16 μW cm −2 .

“…Direct electron transfer reactions between proteins (enzymes) and electrodes have been extensively studied from the viewpoints of both, understanding the fundamental features and for applications as biosensors and biofuel cell [5][6][7][8][9][10][11]. Typically, enzymatic biofuel cell has been focused because of their possibility to harvest energy out of non-toxic and non-combustible compounds like sugar opened the way for glucose biofuel cells [5][6][7][8][9][10][11][12][13][14][15][16]. However, the transfer of electrons involved in the redox reactions to an external circuit is a challenging theme.…”

Fast electron transfer between laccase (Lac) and single-walled carbon nanotubes (SWCNTs) can be achieved at a cholate-modified SWCNT interface. Furthermore, the catalytic reduction of O 2 starts at a high potential, close to the equilibrium redox potential of the O 2 /H 2 O couple. A sodium cholate (SC)-modified electrode interface provides suitable conditions for Lac direct bioelectrocatalysis. In the present study, the SC promotional effect in Lac direct bioelectrocatalysis was investigated using various types of electrode materials. The fully hydrophilic surface of indium tin oxide and an Au electrode surface did not show a SC promotional effect, because SC did not bind to these surfaces. A carbon surface with a large number of defects was unsuitable for SC binding because of hydrophilic functional groups at the defect sites. Carbon surfaces with few defects, for example, basal-plane highly oriented pyrolytic graphite (HOPG), gave a SC promotional effect.

“…Enzymes, antibodies, receptors and microorganisms can be applied as biological sensing elements [4]. Purified enzymes have been used in most biosensor constructions [5][6][7] because of their specificity and sensitivity [8,9] but disadvantages such as instability and expensive parts have limited their range of applications [9]. MFCs provide unique platforms for potentially powering small portable electronic devices, studies of microbes, and screening environmental strains.…”

Miniature microbial fuel cells have recently drawn lots of attention as portable power generation devices due to their short startup time and environmentally-friendly process which could be used for powering small integrated biosensors. We designed and fabricated a microbial fuel cell in a microfluidic platform. The device was made in polydimethylsiloxane with a volume of 4 µL and consisted of two carbon cloth electrodes and proton exchange membrane. Shewanella Oneidensis MR-1 was chosen to be the electrogenic bacterial strain and inoculated into the anode chamber. Ferricyanide was used as the catholyte and pumped into the cathode chamber at a constant flow rate during the experiment. The miniature microbial fuel cell generated a maximum current of 2.59 µA and had a significantly short startup time.
