Self-charging biosupercapacitors
Malmö högskola, Faculty of Health and Society (HS), Department of Biomedical Science (BMV).
2016 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

The thesis is focused on an entirely new class of electric power biodevices –self-charging biosupercapacitors, or in other words, charge-storing biofuelcells. The power generating segments of these biodevices rely on differentredox enzymes electrically wired to electrode surfaces. Planar electrodes wereadditionally nanostructured by gold nanoparticles to increase the real surfacearea/enhance enzyme loading. Bilirubin oxidase was used as a cathodicbiocatalyst responsible for oxygen electroreduction, whereas cellobiosedehydrogenase and glucose dehydrogenase were exploited as anodicbioelements catalyzing electrooxidation of glucose. The charge-storingsegments of biosupercapacitors were based on different electroconductingpolymers, including carbon nanotube based nanocomposites, and osmiummodified redox hydrogels. The particular bioelectrodes were characterized indetail using scanning electron and atomic force microscopies, as well asvarious electrochemical techniques. Self-charging biosupercapacitors wereassembled and basic parameters of the biodevices, viz. open-circuit voltages,power and charge densities, and stability, were studied in continuous andpulse operating modes.

Abstract [en]

We herein report on an entirely new kind of electric power device. In the hybrid device, chemical energy is directly converted into electric energy, which is capacitively stored within a singular contrivance. The device is built based on dual-function electrodes, viz. discrete electrodes manifesting simultaneous electrocatalytic and charge-storage features.

Abstract [en]

Two-in-one: A biological supercapacitor—a combination of an electrochemical capacitor and an enzymatic fuel cell—is presented. Both the capacitor and the biofuel cell are built from nanomaterials, namely, polyaniline/carbon nanotube composites and redox enzyme/gold nanoparticle assemblies. The biosupercapacitor is self-charging, membrane- and mediator-less

Abstract [en]

Hybrid electric power biodevices, a new type of electric power-producing device, are a combination of an electrochemical capacitor and a biofuel cell. In this Minireview, we summarise existing knowledge on double-function bioelectrodes, that is, single electrodes concurrently manifesting bio-electrocatalytic and charge-storage features, and describe important historical aspects and achievements in this area. We also discuss a recently proposed method for concomitant electric power generation and storage, which is exemplified by fabricated and characterised self-charging bio-supercapacitors, also termed charge-storing biofuel cells. The electric power in these hybrid devices is uninterruptedly generated by direct transformation of chemical energy into electric energy, as occurs in biofuel cells. The power is simultaneously and directly stored within a single device, relying on different types of capacitance based on reversible charge-transfer reactions (pseudocapacitance) and/or electric double-layer capacitance, as in electrochemical capacitors. We also present some unpublished results on both dual-feature electrodes and hybrid biodevices and briefly highlight the prospects for their application.

Abstract [en]

In nearly all papers concerning enzyme–nanoparticle based bioelectronic devices, it is stated that the presence of nanoparticles on electrode surfaces per se enhances bioelectrocatalysis, although the reasons for that enhancement are often unclear. Here, we report detailed experimental evidence that neither an overpotential of bioelectrocatalysis, nor direct electron transfer and bioelectrocatalytic reaction rates for an adsorbed enzyme depend on the size of nanoparticles within the range of 20–80 nm, i.e. for nanoparticles that are considerably larger than the enzyme molecules.

Abstract [en]

A review. This work provides an overview of the recent advances in the field of tear-​based wearable electrochem. biodevices, including non-​invasive biosensors, biol. fuel cells and biosupercapacitors. Contact lenses are attractive platforms for fabricating non-​invasive self-​contained gadgets for different applications, starting from devices with casual or mundane purposes only, like personalized smart lenses with direct (invisible for others) displays, and ending with biomedical devices for continuous fitness status and​/or health care monitoring. Key requirements and challenges that confront researchers in this exciting area are discussed.

Abstract [en]

We propose the very first "Nernstian biosupercapacitor", a biodevice based on only one redox polymer: poly(vinyl imidazole-​co-​allylamine)​[Os(bpy)​2Cl]​, and two biocatalysts. At the bioanode PQQ-​dependent glucose dehydrogenase reduces the Os3+ moieties at the polymer to Os2+ shifting the Nernst potential of the Os3+/Os2+ redox couple to neg. values. Concomitantly, at the biocathode the redn. of O2 by means of bilirubin oxidase embedded in the same redox polymer leads to the oxidn. of Os2+ to Os3+ shifting the Nernst potential to higher values. Despite the use of just one redox polymer an open circuit voltage of more than 0.45 V was obtained during charging and the charge is stored in the redox polymer at both the bioanode and the biocathode. By connecting both electrodes via a predefined resistor a high power d. is obtained for a short time exceeding the steady state power of a corresponding biofuel cell by a factor of 8.
