“…The vesicles formed in nonpolar, organic solvents are referred to as “reverse vesicles”, which also have bilayer, shell‐like structures but with the hydrophobic domains of the amphiphiles exposed to the oily medium 2. The reverse vesicles could find applications as carriers for controlled release of hydrophobic solutes 3. However, in comparison to the extensive studies on normal vesicles, the exploration of reverse vesicles, especially related to the rational tuning of the vesicle morphology, is still very limited 2–5.…”

The formation of reverse-vesicular structures of the polyoxometalate-containing hybrid surfactants [nBu(4)N](3)[MnMo(6)O(18){(OCH(2))(3)-CNHCO(CH(2))(n-2)CH(3)}(2)] (Mn-Anderson-C(n), n=6, 16) in nonpolar medium was achieved by titrating toluene into Mn-Anderson-C(n)/acetonitrile (MeCN) solution. Stepwise change of the solvent polarity induces self-association of the hydrophilic Mn-Anderson cluster on the hybrid amphiphiles. The reverse-vesicle formation was characterized by laser light scattering and further confirmed by transmission electron microscopy techniques, and the vesicle sizes increase with increasing toluene contents. The assembly process was accelerated at an elevated temperature. The length of the alkyl tails on the hybrid surfactants has a minor effect on the vesicle sizes, because the strong attraction between the polyoxometalate clusters is more dominant in the reverse-vesicle formation.

“…Several other groups later also formulated reverse vesicles based on sucrose esters, 141 amino acid derivatives, 142 and metalloamphiphiles. 143 However, questions continue to arise regarding the stability, robustness, and ease of formulation of reverse vesicles and the general guidelines for the structure control of such aggregates are unclear.…”

“…So far, the literatures have reported several methods to prepare reverse vesicles including using of salt-free catanionic surfactant mixture [14] , tetraethyleneglycol dodecyl ether [10] , sucrose monoalkanoate [7] , phospholipids mixture [19,20] , organic-inorganic polyoxometalate-containing hybrid surfactants etc [21] . But there are some problems in the preparation of reverse vesicles.…”

Reverse vesicles are the counterparts of normal vesicles, which are the aggregations of molecular bilayers with hydrophilic parts inside and hydrophobic parts outside. As their potential applications in many fields, they have attracted much attention of scientists. In this paper, we demonstrated a novel method to prepare reverse vesicles by through egg phosphatidylcholine (EggPC) membrane and microemulsion solution. Reverse vesicles of EggPC can be constructed quickly on carbon fibers. The formation of vesicles can be easily observed in situ under achromatic objective lens by an inverted optical microscope.It is very convenient to characterize. We investigated the influences of curvature, adsorption effect and hydrogen bond interaction on the formation of reverse vesicles and presented the mechanism.
