摘要
Noncontact atomic force microscopy (NC-AFM) has been employed in order to observe double-stranded DNA (deoxyribonucleic acid) on a Cu(lll) surface. In-situ tip improvement was found to be effective for the NC-AFM measurement. The authors have obtained high-resolution images of double-stranded DNA including the DNA double helix structure using the shape-controlled tip.
