dsDNA molecules deposited on HOPG substrate by using graphite modifier(GM). AFM image is obtained in air with use  NSG01_DLC probe. Notice that the cross-cut size of DNA in the image - 2.6 nm - is very close to its real size - 2 nm. Achieved resolution is the best to date.

Image is obtained and kindly given by  Dr. D.V. Klinov, Shemyakin & Ovchinikov Institute of Bioorganic Chemistry, RUSSIAN ACADEMY OF SCIENCES.
