“…Similarly, iron-sulfur cluster-modified Au or Pt nanoparticles (NPs) were reconstituted into apo-PSI, resulting in the wiring, and H 2 evolution by the hybrid system 45 . Furthermore, the genetically engineered photosynthetic RC was oriented in a monolayer configuration on electrode supports using a His-tag Ni-NTA complex, and the resulting photocurrents in the presence of an electron mediator, were monitored 46,47 . Also, alignment of PSI on electrode surfaces was achieved with the aid of bis-aniline-crosslinked Pt nanoclusters 48 or by using redox polymer matrices as electron-transfer relays 21 .…”

Photosynthesis is a sustainable process that converts light energy into chemical energy. substantial research efforts are directed towards the application of the photosynthetic reaction centres, photosystems I and II, as active components for the light-induced generation of electrical power or fuel products. nonetheless, no integrated photo-bioelectrochemical device that produces electrical power, upon irradiation of an aqueous solution that includes two inter-connected electrodes is known. Here we report the assembly of photobiofuel cells that generate electricity upon irradiation of biomaterial-functionalized electrodes in aqueous solutions. The cells are composed of electrically contacted photosystem II-functionalized photoanodes and an electrically wired bilirubin oxidase/carbon nanotubes-modified cathode. Illumination of the photoanodes yields the oxidation of water to o 2 and the transfer of electrons through the external circuit to the cathode, where o 2 is re-reduced to water.

“…The created redox systems ideally can be made to work, offering numerous chance of application (Giardi and Pace, 2005;Lu et al, 2007). There are successful essays in nano systems as well, for example RC can be bound to carbon nano tubes (Dorogi et al, 2006), to transition metal-oxides (Lu et al, 2005) or other electrode surfaces (Das et al, 2004;Lebedev et al, 2006). In these systems the electron-excited by the light-is trapped in the redox system around the RC and, among other things, it can be part of circuit segments.…”

There is no doubt that studying the photosynthetic conversion of light into chemical energy is extremely important in many points of view: 1) technical-in order to improve the utilization of the solar energy; 2) food production -to improve the photosynthetic production of plants in agriculture; 3) ecology -keeping the primer production in ecosystems in the biosphere balanced, etc. In the photosynthetic reaction centre protein, RC, light energy is converted by a quantum yield of almost unity. There is no such a system designed by human which is able to do that. The RC purified from purple bacteria provides an extremely unique system for studying the requirements for high efficiency conversion of light into electrochemical energy. Thanks to the recent structural (e.g. crystallography (Nobel prize to Michel, Deisenhofer, Huber) and functional (Nobel prize to Marcus)) results together with the works of molecular biology, computerand electro-techniques, a wealth of information made a relatively clear picture about the kinetics, energetics and stabilization of electron transport within this protein that opens possibilities for new generation practical applications. In this paper we provide a short summary of fields in which the reaction centre protein can be important from practical points of view.

Major preoccupations of this work have been the development of strategies for effective interfacing of the positive and negative terminals of the photovoltaic protein to the working and counter electrode, either through direct binding or the use of diffusional mediators [4][5][6][7][8][16][17][18][19][20][21][22][23][24][25][26][27]. In the case of RC's from purple bacteria a particularly effective strategy has been to use analogues of the natural electron donor and electron acceptor, cytochrome (cyt) c2 and ubiquinone-10 (UQ10), to connect the photovoltaic protein to the two electrodes [18,20,22,[27][28][29].…”
