"DNA nanostructures : principle and motivations"

Abstract

In this presentation that we plan to be introductory we will present the recent field of DNA origami. We will explain how to assemble by using simple sets of thermodynamic rules 2D and 3D shapes of few nanometers. Interestingly although we exactly know how to program the self-assembly of a given shape and engineer it we know very little on the process itself : what is the pathway ? Our current research focuses on this question and we will present our methodology and recent results on models structures using thermodynamic methods. We will open the field in giving our motivations to explore and design rationally the folding pathways. Beside fundamental thermodynamics, these motivations lies in molecular robotics, information processing and eventually in computing.
