A Tandem Solar Biofuel Cell: Harnessing Energy from Light and Biofuels
Abstract We report on a photobioelectrochemical fuel cell consisting of a glucose‐oxidase‐modified BiFeO3 photobiocathode and a quantum‐dot‐sensitized inverse opal TiO2 photobioanode linked to FAD glucose dehydrogenase via a redox polymer. Both photobioelectrodes are driven by enzymatic glucose conversion. Whereas the photobioanode can collect electrons from sugar oxidation at rather low potential, the photobiocathode shows reduction currents at rather high potential.
Electroenzymatic Nitrogen Fixation Using a MoFe Protein System Immobilized in an Organic Redox Polymer
Abstract We report an organic redox‐polymer‐based electroenzymatic nitrogen fixation system using a metal‐free redox polymer, namely neutral‐red‐modified poly(glycidyl methacrylate‐co‐methylmethacrylate‐co‐ poly(ethyleneglycol)methacrylate) with a low redox potential of −0.58 V vs. SCE.
Improved quantum efficiency in an engineered light harvesting/photosystem II super-complex for high current density biophotoanodes
Improved quantum efficiency in an engineered light harvesting/photosystem II super-complex for high current density biophotoanodes Photosystem II (PSII) is the only enzyme that catalyzes light-induced water oxidation being the basis for its application as a biophotoanode in various bio-photovoltaics and photo-bioelectrochemical cells.

An O2 Tolerant Polymer/Glucose Oxidase Based Bioanode as Basis for a Self‐Powered Glucose Sensor
The development of O tolerant glucose sensors based on the highly active and robust enzyme glucose oxidase is still a major challenge because of the competition between the natural electron acceptor O and free‐diffusing or polymer‐bound artificial electron acceptors. We report the fabrication of a glucose oxidase based bioanode that operates under ambient conditions.
Dual properties of a hydrogen oxidation Ni-catalyst entrapped within a polymer promote self-defense against oxygen
The catalyst was dispersed into a poly(glycidyl methacrylate-co-butyl acrylate-co-poly(ethylene glycol) methacrylate) (denoted as P(GMA-BA-PEGMA) in the following) polymer (See Methods section)). This polymer was chosen because of its rather hydrophobic nature that allows for the formation of stable films in aqueous electrolytes. Moreover, the polymer backbone consists of chemically inert and non-coordinating monomers.
