The aim of this work is to investigate the driving forces involved in amino acid solubilization in cationic reversed micelles, and to determine in which way different parameters affect the reversed micellar structure and amino acid solubilization, in order to select the best conditions to optimize amino acid extraction. To this end, extraction equilibrium experiments were performed using different experimental conditions and three amino acids with different structures: aspartic acid ± a hydrophilic amino acid, phenylalanine ± a slightly hydrophobic amino acid, and tryptophan ± a hydrophobic amino acid. The study of the effect of amino acid related parameters, such as pH and the initial amino acid concentration in the aqueous phase, and the effect of parameters that in¯uence the reversed micellar structure, such as surfactant concentration, ionic strength and co-surfactant concentration, provides useful information about the driving forces involved, solute±micelle interfacial interactions and solute location in the cationic system trioctylmethylammonium chloride (TOMAC)/ hexanol/n-heptane. These parameters can be adjusted to optimize amino acid extraction. It is shown that amino acids with the same isoelectric point can be selectively separated by exploring the different interactions they establish with the reversed micellar interface.

“…Solid microcapsules loaded with bioactive polymers are also prepared from W/O/W droplets by the solvent evaporation method [16][17][18][19]. Other applications studied thus far include the synthesis of composite microspheres [20] and the use of an intermediate phase as a permeable membrane in separation technology [21][22][23][24][25][26].…”

The preparation of multiple emulsions with controlled droplet sizes and internal structures has been a challenge for a long time. However, in recent years, a major breakthrough has been achieved in the preparation of monodisperse single emulsions by small-scale fluid processing, which has enabled the formation of multiple emulsions with the desired droplet sizes, structures, and compositions. This review deals with the preparation of controlled multiple emulsions in various microstructured devices. The four preparation pathways are discussed individually. They are (a) membrane emulsification, (b) microchannel emulsification, (c) the use of a two-dimensional microfluidic device, and (d) the use of a three-dimensional coaxial microcapillary device. The applications of the prepared multiple emulsions to a novel class of materials are also discussed.
