Biological photonic crystals: diatoms for the control of absorption and emission of light

Fachliche Zuordnung Physik der kondensierten Materie
Förderung Förderung von 2003 bis 2006
Projektkennung Deutsche Forschungsgemeinschaft (DFG) - Projektnummer 5403139
 
The project aims at the application of photonic crystals of biological origin for controlling the adsorption and emission of light. As prototypical example, the diatom Coscinodicus granii is chosen, the silicea cell wall of which exhibits a very regular hexagonal pore structure. The chemical structure of the cell wall allows covalent junctions for implementation into silicon microtechnology and the attachment of functional organic dyes as optically active components. In the project, the light path within a diatom cell structure and the local efficiency of light adsorption and emitting is investigated. The possibility of obtaining determined feature sizes by means of cell culivation will be explored.
