T4 DNA condensation in water-alcohol media
M. O. Gallyamov, O. A. Pyshkina, V. G. Sergeyev +1
The process of compaction of high molecular weight DNA T4 is investigated directly in a AFM liquid cell. The AFM-images of globules formed by DNA molecules in the result of compact…
Quantitative methods for deconvolution of true topographical properties of object on the basis of measured AFM-images: Part 2. Broadening effect
M. O. Gallyamov, I. V. Yaminsky
Technique of the quantitative description of image broadening effect in AFM allowing to restore real geometrical parameters of object using two-parameters model (height and width a…
Quantitative methods for deconvolution of true topographical properties of object on the basis of AFM-images: Part 1. Contact tip-sample deformations
M. O. Gallyamov, I. V. Yaminsky
We assume that the sample height measured using AFM is reduced due to contact deformation. The Herz contact theory is applied for the quantitative description. General numerical so…
Scanning probe microscopy of nucleic acids and thin organic films
Marat Olegovich Gallyamov
We developed the models and algorithms to describe two main artefacts of AFM: (i) broadening effect and (ii) decreased heights of profiles for individual objects adsorbed on a hard…
Visualization of atomic structure using AFM: theoretical description
M. O. Gallyamov, I. V. Yaminsky
We suggest simple model of image formation in atomic force microscope (AFM) taking into account contact deformations of probe and sample during scanning. The model explains the pos…
