Recent advances in biosurfactant-based association colloids—Self-assembly in water

Recent studies of self-assembly in binary systems bio-surfactants, either microbial origin or saponins extracted from plants, are reviewed. Saponins water reported the first section include aescin, glycyrrhizin, and quillaja saponins, while rhamnolipids discussed second on surfactants. Studies surface activities a natural starting point characterization surfactants, but here we focus mainly physico-chemical structural properties self-assembled bulk structures solution, often characterized by scattering techniques. When quantitative modelling is performed, parameters like aggregation numbers, head group areas, resulting shapes can be followed as function physical-chemical concentration, composition, temperature, pH. Morphologies micelles their evolution with addition other bio- synthetic co-surfactants, proteins phospholipids.
