3. Statistical mechanics of DNA adsorption on a carbon nanotubeSh. A. Tonoyan, Davit Khechoyan, Yevgeni S. Mamasakhlisov, Artem Badasyan, 2020, objavljeni povzetek znanstvenega prispevka na konferenci Opis: The attraction between the polycyclic aromatic surface elements of carbon nanotubes (CNT) and the aro-
matic nucleotides of deoxyribonucleic acid (DNA) leads to reversible adsorption (physisorption) between
them. With the goal to provide the theoretical support to numerous technologies on the basis of DNA-CNT
hybrids, we propose a Hamiltonian formulation for the zipper model that accounts for relevant interactions
and allows for the processing of experimental data, which has awaited an available theory for a decade. Najdeno v: osebi Ključne besede: DNA, CNT Objavljeno: 22.05.2020; Ogledov: 1378; Prenosov: 68

5. Implicit water model within the Zimm-Bragg approach to analyze experimental data for heat and cold denaturation of proteinsJože Grdadolnik, Matjaž Valant, Sh. A. Tonoyan, Artem Badasyan, 2021, izvirni znanstveni članek Opis: Studies of biopolymer conformations essentially rely on theoretical models that are routinely
used to process and analyze experimental data. While modern experiments allow study of
single molecules in vivo, corresponding theories date back to the early 1950s and require an
essential update to include the recent significant progress in the description of water. The
Hamiltonian formulation of the Zimm-Bragg model we propose includes a simplified, yet
explicit model of water-polypeptide interactions that transforms into the equivalent implicit
description after performing the summation of solvent degrees of freedom in the partition
function. Here we show that our model fits very well to the circular dichroism experimental
data for both heat and cold denaturation and provides the energies of inter- and intra-
molecular H-bonds, unavailable with other processing methods. The revealed delicate
balance between these energies determines the conditions for the existence of cold dena-
turation and thus clarifies its absence in some proteins. Najdeno v: osebi Ključne besede: protein folding, cold denaturation, water, Zimm-Bragg model Objavljeno: 06.05.2021; Ogledov: 906; Prenosov: 3
