Abstract

We describe a procedure for imaging DNA molecules using atomic force microscopy (AFM). Double-stranded DNA binds to a mica surface modified by treatment with 3- aminopropyltriethoxysilane to yield AFM images that are stable under repeated scanning. We used this procedure to obtain high quality images of unstained linear DNA molecules and circular DNA molecules. The resolution was limited to tens of nanometers by the profile of the AFM tips.
