Atomic Force Microscopy (AFM) opens new perspectives in the study of DNA-protein interactions. My work consisted of developing new methodologies for controlling DNA adsorption on surfaces and enabling the study of the dynamics of the complexes in liquid. We have characterized the interactions between DNA and the mica surface. We propose a simple model to describe the electrostatic interactions in solution between DNA and mica, considering the role of monovalent and divalent cations. The good correlation with experimental data allows validating referential adsorption conditions and a reversible adsorption method for DNA on nickel-pretreated mica. In parallel we have developed a system of tethers to anchor DNA by its extremities. The control ...
