摘要

We use a carbon nanotube (CNT) probe to observe the details in double-stranded deoxyribonucleic acid (DNA) and proteins under atomic force microscopy (AFM) tapping mode in air. The DNA has periodic helical turns of approximately 4 nm interval. Fine ring like and helical structures in the proteins adsorbed on graphite have also been resolved. These results cannot be reproduced using conventional AFM silicon probes. The superiority of the CNT probe applied with the AFM tapping mode lies in both the unique mechanical and chemical properties of the carbon nanotube, and in our ability to tailor the length and adjust the angle of the CNT probe attached to a commercial AFM tip.
