suggested, that interaction of amphiphiles with DNA decamer is predominantly driven by cooperative electrostatic interactions. Membranotropic properties of novel amphiphiles could be regulated by the change of the length of hydrophobic tail; with these properties being the more markedly expressed in the case of the lower homologue.

The invention provides methods for preparing composites of polyester and layered compounds. In one embodiment, the invention provides a method for preparing a composite of a poly(alkylene terephthalate) and a cation-modified layered compound via in-situ polycondensation in solvent. In another embodiment, composites are made with polyesters of average molecular weight of 10,000 g/mol or more by mixing the polyester and a layered compound in the presence of a solvent, such as ortho-dichlorobenzene.

elongation of the length of hydrophobic tail by four methylene units. Estimation of interaction of amphiphiles with biological objects has revealed, that all compounds exhibit high bacteriostatic and bactericide properties preferably toward gram-positive strains, as well as they have lowhemolyticactivity at active concentrations. Antibacterial properties of tetradecyl amphiphilic derivative have surpassed

The study on aggregation capacity of novel imidazolium-containing amphiphiles of 1-(2-hydroxyethyl)alkylimidazolium bromide series and their interaction with bio-objects (DNA decamer, bovine serum albumin, phospholipid) was performed. It was revealed that introduction of hydroxyethyl moiety into the surfactant molecule resulted in 1.5–2-fold decrease of critical micelle concentration. These modified
