A simple route for immobilizing linear DNA double-strands is described on p. 338 by B. Chénais, J.-F. Pilard et al. Surface modification by electrografting of an aryldiazonium salt yields a roughness of 0.2 nm. The low roughness obtained by the modification permits visualization by AFM of dsDNA and complexes of dsDNA with a protein.
