Covalent and Non‐Covalent DNA–Gold‐Nanoparticle Interactions: New Avenues of Research
ChemPhysChem, 2016AbstractThe interactions of DNA, whether long, hundred base pair chains or short‐chained oligonucleotides, with ligands play a key role in the field of structural biology. Its biological activity not only depends on the thermodynamic properties of DNA–ligand complexes, but can and often is conditioned by the formation kinetics of those complexes.

Non Covalent Interactions In Protein Complexes
2007While the electrostatic interactions between the complementary charged proteins increase their interaction, desolvation of the charged and polar amino acid residues destabilizes the protein - protein complex. We studied influence of the electrostatic interactions on formation of the protein complexes between Ras and Rap and their effectors Raf and ...

Interatomic interactions in covalent and ionic solids
Physical Review B, 1990The total energy in tight-binding theory is obtained to second order in the ratio of the width of the bonding band to the bonding-antibonding splitting. This is the reciprocal of the expansion parameter appropriate to metals. No other important approximation on the minimal-basis, nearest-neighbor, tight-binding Hamiltonian is required for the periodic ...

Non-covalent interactions – QTAIM and NBO analysis
Journal of Molecular Modeling, 2012MP2(full)/6-311++G(3df,3pd) calculations were carried out on complexes linked through various non-covalent Lewis acid - Lewis base interactions. These are: hydrogen bond, dihydrogen bond, hydride bond and halogen bond. The quantum theory of ´atoms in molecules´ (QTAIM) as well as the natural bond orbitals (NBO) method were applied to analyze properties

Shifting Paradigms: Electrostatic Interactions and Covalent Bonding
Chemistry – A European Journal, 2010AbstractThe role of electrostatic interactions in covalent bonding of heavier main group elements has been evaluated for the exemplary set of molecules X2H2 (X=C, Si, Ge, Sn, Pb). Density functional calculations at PBE/QZ4P combined with energy decomposition procedures and kinetic energy density analyses have been carried out for a variety of different

Non-covalent interactions between proteins and polysaccharides
Biotechnology Advances, 2006Foods with novel or improved properties can be created by utilizing non-covalent interactions between proteins and polysaccharides. In solution, either attractive or repulsive interactions between proteins and polysaccharides can be used to create microstructures that give foods novel textural and sensory properties.
