Novel sugar-based gemini surfactants: aggregation properties in aqueous solutiony
Gemini or dimeric surfactants can in principle be viewed as two conventional surfactants connected via a spacer at the level of the polar headgroups. A novel class of sugar-based gemini surfactants with rich and intriguing aggregation behavior in aqueous solution is the focus of this mini-review. The headgroup of the geminis consists of reduced sugars (glucose or mannose) connected to tertiary ...
متن کاملpH-Dependent aggregation properties of mixtures of sugar-based gemini surfactants with phospholipids and single-tailed surfactants.
Sugar-based gemini surfactants (GSs) display rich pH-dependent phase diagrams and are considered to be promising candidates as gene- and drug-delivery vehicles for biomedical applications. Several sugar-based GSs form vesicles around neutral pH. The vesicular dispersions undergo transitions toward wormlike micelles and spherical micelles at acidic pH, whereas flocculation followed by redispersi...

متن کاملPhysicochemical properties of oleic acid-based partially fluorinated gemini surfactants.
We have developed oleic acid-based partially fluorinated gemini surfactants with carboxylic acid headgroups. The fluorocarbon chain is covalently bound to the terminal carbonyl group of oleic acid via a -CH(2)CH(2)OCO- unit, and the carboxylic acid headgroups are introduced to the cis double bond of oleic acid via -OCOCH(2)CH(2)- units. The aqueous solution properties of these surfactants were ...
متن کاملInterfacial Properties of Sugar-based Surfactants
Motivation Interest is growing in the development of material technologies that are based on renewable resources. The use of biomass as feedstock is of expanding industrial significance, particularly in the energy and commodities sectors. Relative to these arenas, monoand polysaccharides, very flexible and tunable chemical starting materials, are estimated to make up three-quarters of the world...
