Assembly of photo-bioelectrochemical cells using photosystem I-functionalized electrodes

A Polymer Multilayer Based Amperometric Biosensor for the Detection of Lactose in the Presence of High Concentrations of Glucose

“…For all aqueous solutions, water from a Milli‐Q (Millipore) purification system was used. Poly(1‐vinylimidazole‐co‐allylamine)‐[Os(bpy) 2 Cl]Cl (bpy=2,2’‐bipyridine) was synthesized according to and was used for the wiring of GOx in the determination of the glucose content of lactose‐free milk.…”

Optical Shading Induces an In‐Plane Potential Gradient in a Semiartificial Photosynthetic System Bringing Photoelectric Synergy

“…With new developments in materials and methods for the conversion of solar energy into electric power and chemical fuels, photovoltaic and photo-electrochemical technologies are rapidly progressing enzymes/proteins [22][23][24][37][38][39][40][41][42][43][44][45][46][47][48] with diverse synthetic materials including bulk semiconductors, [49,50] semiconductive nanowires, [51,52] quantum dots, [53] and plasmonic metal nanostructures.

“…[10][11][12][13][14] The "biomimetic solar cell," an application long sought after, aims to mimic the architecture of nature's reaction center (RC) and light-harvesting (LH) complexes in a fully artificial photosynthetic device for direct "solar electricity" generation. [18] Alongside the development of artificial photosynthetic systems, there have also been attempts to directly employ natural photosynthetic materials such as bacterial cells, [19][20][21] pigment proteins, [22][23][24][25][26][27][28][29] and membranes [30,31] as photoactive components for both direct electricity generation and fuel molecule synthesis.While, on the one hand, fully artificial photosynthetic systems lack the nanoscale architectural sophistication found in natural photosystems, on the other hand, natural photosystems are not always sufficiently robust or efficient outside their native environments.

Wiring of Photosystem I and Hydrogenase on an Electrode for Photoelectrochemical H2 Production by using Redox Polymers for Relatively Positive Onset Potential

“…Several studies targeting the connection of PSI to electrodes for photocurrent generation, based on direct electron transfer (DET) or mediated electron transfer (MET), have been published . In many cases PSI is integrated in cross‐linked redox hydrogels . A particularly interesting study involved the co‐immobilization of PSI and Pt nanoparticles on an Os‐complex redox polymer over an electrode for light‐induced H 2 evolution.…”
