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

该项目旨在应用生物来源的光子晶体来控制光的吸收和发射。作为典型例子，选择了硅藻Coscinodicus ranii，其硅藻的细胞壁表现出非常规则的六角孔结构。细胞壁的化学结构允许在硅微技术中实现共价连接，并将功能性有机染料作为光学活性成分进行附着。在该项目中，研究了硅藻细胞结构中的光路和光吸收和发射的局部效率。将探索通过细胞培养获得确定的特征大小的可能性。

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.
