Daniel Aron Gudnason.

During his studies, Daniel Aron Gudnason researched DNA functionalized conjugated polymers. Conjugated polymers are a photo- and electroluminescent type of polymer with conformationally dependent photophysical properties, typically used in research for photovoltaic devices such as organic light emitting diodes and solar cells. DNA functionalized polymers are conjugated polymers with a specific sequence of DNA covalently attached to each monomeric unit, making them compatible with DNA nanotechnology. Daniel has studied how to control the conformation and therefore the fluorescent properties of a DNA functionalized conjugated polymer through the use of ionic and DNA based interactions, at the ensemble and single molecule level. With the ability to control the materials fluorescent properties, the performance of the polymer in DNA based light harvesting and photonic wiring was also investigated as a function of polymer conformation.

These findings contribute with insights into the behavior and use of DNA functionalized conjugated polymers in DNA nanotechnology, and how to optimize the polymers’ fluorescent properties in such applications.

The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO), Science and Technology, Aarhus University.

The resumé was prepared by the PhD student.
