Images of the sequence of fragments of a biopolymer molecule have been obtained using scanning tunneling microscopy under native conditions (air atmosphere) with bacterial DNA as the model object. Air adsorbate (mostly formed by water vapors) coating the molecules increases the local tunnel conductivity; selective adsorption indirectly reflects the local conductivity of the fragments composed by different...
An analytical model showing the effect of adsorbed air on the resolution of biological nanoparticles in atomic-force microscopy is developed. It is found that the lateral topographic sizes of images of biological nanoparticles do not reflect their actual transverse sizes and are mainly required to determine the object length and configuration on the substrate. It is shown that the height (diameter)...
