Using the Sunlight for Biocyatalysis – Development of Photo-Bioelectrode-Structures for Synthesis Isolation, Stabilization, Modification and Assembly of Photosystems and Its Components in Hybrid-Assemblies for Photo-Biocatalysis
The aim of the Tamdem-project is to develop light-activated electrode devices for biocatalytical purposes. Therefore photosystems or components should be combined with electrodes for an efficient photo-electron transfer. By coupling various enzyme systems with light-activated electrodes, the produced photocurrent enables the synthesis of valuable substances. To achieve this, functional hybrid-structures from anorganic and biological components should be applied on electrodes.
The two main objects of our project are i) coupling isolated photosystems or light-harvesting complexes with nano-based electrodes and ii) combination of those systems with biocatalytical reactions. Prerequisite for this is the efficient coupling of light-harvesting by the used protein complexes and generating photo-current at the electrode. Additionally, we are using generated charge carrier at the protein-electrode for further biochemical reactions. Based on this combining biocatalytical reactions with photo-activated electrodes results in light- and voltage guided synthesis of biochemical valuables.
