英文摘要Self-assembled monolayer of a double-stranded dna, which was formed by a 20-nt 5'-thiol-modified oligonucleotide at the interface of au(111)/solution, has been imaged and studied with electrochemical scanning tunneling microscopy (ecstm). the results showed that the preferred directions of the adsorbed dna were <110> and <112>. the measured width of the dna stripes was 0.95+/-0.02 nm, which was consistent with the width of dsdna base pairs. the contour of dna in the stm image consisted of a series of blobs, which were due to the anchoring of the bases to the substrate along the dsdna chain. the imaging of a large-scale array of dna lying flat on the substrate offers a convenient method for the further application of high-resolution stm to the study of the interaction between dna and a variety of molecules.
