Title: Nature as Technology: Strategies for Nano-Scale, DNA-Based Communication
Tweeter: Jonas Hannestad, @jhannestad, PhD student at Chemical and Biological Engineering at Chalmers University of Technology, Gothenburg. Jonas works with bio-inspired nanotechnology, with a particular focus on nano-scale photonic devices.
Description: Natural systems often display remarkable nano-scale architectures, built through self-assembly. These complex, supramolecular, structures, whose emergent properties to a great extent depend on the spatial organization of the comprising molecules, perform a vast number of functions within the biological cell. We utilize the working principles behind natural light harvesting complexes from photosynthetic bacteria together with the programmability of the four-letter alphabet of DNA to create devices for optical communication on the nanometer scale.
