Conference talk: “self-assembled DNA-based photonic devices”

I’m speaking at the conference Fluorescent Biomolecules and their Building Blocks – Design and Applications held in Gothenburg. The conference takes place between July 5 and July 8 and I will give my talk on the final day. The focus of the conference is mainly on how fluorescent biomolecules (such as e.g. fluorescent proteins or fluorescent nucleic bas analogs) can be utilized in biological systems to provide new insights into their functionality. A part of the program is also dedicated to fluorescence in nanotechnology.

I will talk about how fluorescence and Förster resonance energy transfer (FRET) can be used in self-assembled DNA-based nano-assemblies, not as probes, but as function in themselves. The content is outlined in the short abstract below.

Using the principle of self-assembly, we have constructed fluorescence-based photonic devices capable of both energy and electron transfer. DNA and dye assemblies are created to conduct long range and branched excitation energy transfer as well as light harvesting operations where excitation energy is transferred from multiple donors to a single acceptor capable of electron transfer. This provides a versatile platform for novel photonic devices relying on bottom up assembly
