Objective(s): The purpose of this study was investigation of the protein corona formation on the surface of zwitterionic nanoparticles when they exposed to bio-fluid like human plasma.Methods: Silica nanoparticles with zwitterionic surface coating, cysteine and sulfobetaine were employed as zwitterionic ligands, were synthesized and characterized in terms of physicochemical properties. To...

This work investigates the effect of dilution on phase separation process binary charged polysaccharide–surfactant mixtures formed by two cationic polysaccharides and up to four surfactants different nature (anionic, zwitterionic, neutral), as well potential impact dilution-induced formation conditioning deposits surfaces, mimicking negative charge wettability damaged hair fibers. The results o...

The limiting solubility of fatty acids in micellar solutions of the anionic surfactant sodium laurylethersulfate (SLES) and the zwitterionic surfactant cocamidopropyl betaine (CAPB) is experimentally determined. Saturated straight-chain fatty acids with n=10, 12, 14, 16, and 18 carbon atoms were investigated at working temperatures of 25, 30, 35, and 40°C. The rise of the fatty acid molar fract...

Thermodynamic features related to preparation and use of self-assemblies formed between multilamellar and unilamellar zwitterionic liposomes and polynucleotides with various conformation and sizes are presented. The divalent metal cation or surfactant-induced adsorption, aggregation and adhesion between single- and double-stranded polyribonucleotides and phosphatidylcholine vesicles was followe...

BACKGROUND Surfactants are a class of amphiphilic surface active compounds that show several unique physical properties at liquid-liquid or liquid-solid surface interfaces including the ability to increase the solubility of substances, lower the surface tension of a liquid, and decrease friction between two mediums. Because of these unique physical properties several in vitro, ex vivo, and huma...

Dynamic surface tensions of two types of heterogemini surfactants with nonidentical hydrophilic headgroups consisting of a quaternary ammonium salt (cationic) and a gluconamide (nonionic) or sulfobetaine (zwitterionic) group were measured using the maximum bubble pressure method. For these compounds, effects of alkyl chain length, structure of the hydrophilic groups, and surfactant concentratio...

BACKGROUND The objective of this study was to compare the transfection efficiency of anionic liposomes coated with polyethylenimine (PEI) with that of PEI and Lipofectamine 2000(™) using the plasmid DNA encoding green fluorescent protein in a human hepatoma (Huh7) cell line. METHODS Factors affecting transfection efficiency, including type of surfactant, ratio of phosphatidylcholine (PC)/surf...
