The thermodynamics of conventional surfactants, block copolymers and their mixtures in water was described to the light of the enthalpy function. The two methodologies, i.e. the van't Hoff approach and the isothermal calorimetry, used to determine the enthalpy of micellization of pure surfactants and block copolymers were described. The van't Hoff method was critically discussed. The aqueous co...

Thermodynamics of the binding of antibiotic streptomycin to bovine serum albumin have been studied using isothermal titration calorimetry in combination with fluorescence, UV–vis and circular dichroism spectroscopies. The values of van’t Hoff enthalpy calculated from the temperature dependence of the binding constant do not agree with the calorimetric enthalpies indicating temperature dependent...

Interaction between aspartic acid and D-glucose, D-galactose, and D-fructose has been studied by isothermal titration calorimetry, calorimetry of dissolution, and densimetry. It has been found that D-glucose and D-fructose form thermodynamically stable associates with aspartic acid, in contrast to D-galactose. The selectivity in the interaction of aspartic acid with monosaccharides is affected ...

A novel class of thymine, adenine and lipoamino acid based non-viral carriers for gene delivery has been developed. Their ability to bind to DNA by hydrogen bonding was confirmed by NMR diffusion, isothermal titration calorimetry and transmission electron microscopy experiments.

A novel technique to estimate the distribution state of carboxyl groups within submicron-sized, carboxylated polymer particles was proposed. For the purpose, carboxyl groups in two kinds of butyl methacrylate-methacrylic acid copolymer emulsion, which were prepared by emulsion copolymerizations with different monomer addition methods, were titrated by isothermal titration calorimetry with an ex...

DNA double helices comprising two neighbouring artificial imidazole-Ag(I)-imidazole base pairs incorporate the Ag(I) ions in a cooperative fashion. Isothermal titration calorimetry data confirm the theoretically predicted binding stoichiometry and indicate that Ag(I) binds with association constants >10(6) M(-1) to the metal-free DNA duplex.
