Functional biohybrid materials: Centric diatoms with incorporated donor-acceptor laser dye couplesLukas Selzer, Michael Grimann, and •Thomas Fuhrmann-Lieker — University of Kassel, Institute of Chemistry and Center for Interdisciplinary Nanostructure Science and Technology, 34109 Kassel, Germany

Centric diatoms are unicellular algae with an intricate cell wall of silica that can be described as a photonic crystal slab waveguide. The photonic function can be enhanced by the incorporation of laser dyes, turning the living algae into active fluorescent light-emitters. In order to increase the photoluminescence efficiency, we achieved dual in-vivo-staining with a dye pair for fluorescence resonant energy transfer (FRET). In addition to applications in photonics, this method allows the determination of the acceptor dye concentration in the hybrid material.
