“…Luo and Eisenberg 85 showed how also binary organic solvent systems can be used to influence the size. Furthermore the presence of additives like dendrimers, 88 (homo)polymers 10 and surfactants 89 have been shown to influence the average polymersome size and polydispersity. 10 Finally polymersomes can be resized after they have been formed.…”

Polymeric vesicles in biomedical applications

Polymeric vesicles, or polymersomes, are nano-to micrometre sized polymeric capsules with a bilayered membrane. Applications of these vesicles are foreseen in nanomedicine, in vivo imaging and drug delivery. These applications put many restrictions on the choice of polymer, the size and the surface of the vesicle. In this respect much can be learned and translated to polymersome science from lines of research with a longer history of practical knowledge such as liposomal formulation and polymer drug conjugation. The dimensions of a vesicle, such as size and shape can be controlled for polymersomes and will influence the in vivo circulation time. The surface can be adjusted to induce stealth character, or chemically modified to introduce targeting moieties. And last but not least the choice of block copolymers-the building blocks of a polymersome-can introduce features like biocompatibility, inherent or induced permeability and triggered release. In this review we will discuss the recent advances in polymersome science with regard to biomedical applications and will specifically address the abovementioned features which affect their biological behaviour.

“…MLVs were mainly found to form spontaneously from the micellar phase in catanionic and zwitterionic surfactant solutions. [24,25,26,27,28] Despite decades of research into phase behaviour of LAS and its numerous industrial applications, fundamental understanding of LAS phase behaviour at lower concentrations and temperatures remains elusive. At such concentrations (< 30 wt%), the behaviour of aqueous solutions of LAS is estimated by extrapolation of the trends from solutions of higher concentration.…”

This paper deals with the effect of the surfactant isomeric structure on self-aggregation in aqueous solution. The relationship between the molecular structure of a series of tetradecylbenzene sulfonate isomers (with the benzene ring located at different positions along the alkyl chain) and surface tension was made clear. It is found that the critical micelle concentration increases and the surface tension at critical micellar concentration decreases as the benzene group moves toward the center of the alkyl chain. The structure of micelles was studied by 1 H-NMR relaxation, which indicates that the density of methylene protons in the surface layer of the micellar core decreases as the branching of the hydrophobic group increases. The spontaneous vesicle formation in aqueous solution was investigated by transmission electron microscopy. The results reveal that, as the benzene group moves toward the center of alkyl chain, the assembly structure changes from micelle to vesicle, then to lamellar bilayers, while the critical packing parameter increases.
