Abstract: DNA/octadecylamine(ODA) monolayers were transferred onto silicon substrates and the morphologies of the monolayers were investigated by Atomic Force Microscope(AFM). AFMimages show that the morphologies of DNAdissolved in pure water are very different from those of DNAdissolved in the NaCl solution. When DNAmolecules are dissovled in pure water, they will form ball-like structure in the monolayer. When the DNAmolecules are dissolved in NaCl solution, they will form bunch lines. This DNAline offers a valuable template to direct the formation of unique inorganic nanomaterials.

Key words: LB technique, DNA molecule, Atomic Force Microscope(AFM)
