Drug‐Induced Micelle‐to‐Vesicle Transition of a Cationic Gemini Surfactant: Potential Applications in Drug Delivery

An impetus for the sustained interest in the formation of vesicles is their potential application as efficient drug-delivery systems. A simple approach for ionic surfactants is to add a vesicle-inducing drug of opposite charge. In ionic gemini surfactants (GSs) two molecules are covalently linked by a spacer. Regarding drug delivery, GSs are more attractive candidates than their single-chain counterparts because of their high surface activity and the effect on the physicochemical properties of their solutions caused by changing the length of the spacer and inclusion of heteroatoms therein. Herein, the effect of the (anionic) anti-inflammatory drug diclofenac sodium (DS) on the morphology of aqueous micellar aggregates of gemini surfactant hexamethylene-1,6-bis (dodecyldimethylammonium) dibromide (12-6-12) at 25 °C is reported. Several independent techniques are used to demonstrate drug-induced micelle-to-vesicle transition. These include UV/Vis spectrophotometry, dynamic light scattering, TEM, and small-angle neutron scattering. The micelles are transformed into vesicles with increasing [DS]/[12-6-12] molar ratio; precipitation of the catanionic (DS-GS) complex then occurred, followed by partial resuspension of the weakly anionic precipitate. The stability of some of the prepared vesicles at human body temperature shows their potential use in drug delivery.

“…(d)), respectively. For the PCB synthesized without surfactant, the formation of the spherical PCB particles from interfacial polymerization occurs from the vesicles formed from carbazole monomers . Radical carbazole monomers are formed by the oxidation of the monomers near the interface between HCl and DCM where polymerization takes place initially within the carbazole micelles .…”

Polycarbazole (PCB) was synthesized via an interfacial polymerization method using carbazole monomer and ammonium persulfate as the oxidizing agent. The effects of surfactant type (non‐ionic Tween 20, cationic cetyltrimethylammonium bromide (CTAB) and anionic sodium dodecylsulfate) and concentration on the synthesized PCB were investigated based on the roles of micelle formation. Electron microscopy images revealed various PCB morphologies depending on the surfactant type and concentration. The newly found morphological structures of the PCB were macroporous honeycomb, connected hollow sphere and smaller hollow sphere depending on the surfactant type. The highest electrical conductivity of doped PCB_CTAB obtained was 11.3 ± 0.36 S cm−1. The electrical conductivity values of the doped PCB synthesized with CTAB were higher than that without a surfactant by three orders of magnitude. © 2016 Society of Chemical Industry

“…For ternary mixtures (Holland and Rubingh,1983) proposed a theory that is also quite simple and useful. We have also used it in our studies (Basu Ray et al, 2007a; Ghosh and Moulik, 1998; Pan et al, 2015; Sulthana et al, 2000). All these theories are concerned about the bulk compositions of the mixed surfactant systems mixed in different proportions along with their synergistic and non‐synergistic interactions for determining the thermodynamic properties of the components in solution.…”

Critical micelle concentration (CMC) is a fundamental physical parameter of surfactant aggregation in solution. The CMC is determined by different methods, tensiometry, conductometry, microcalorimetry, fluorimetry, and so on. However, it is known that though CMC is reported as a single value, in reality, micelle formation occurs over a narrow range of concentration for different experimental procedures produce different results. We shall discuss about a unique procedure of measuring correct CMC applicable to all potential methods used in practice. This is essential for the evaluation of thermodynamic properties of the micelle forming process in pure and mixed states in terms of solution theories. As we in this short documentary want to deal with various aspects of Milton Rosen's research-wherein we have also worked-a few other facets of surfactant chemistry research, besides the micelle formation, are also briefly discussed. In mixed surfactant systems, synergistic effects in various surfactant properties like detergency, foaming, solubilization, and so on are found whereas in some others non-synergistic effects are observed. Dehydration of micelles with an increase in temperature or by the addition of hydrophilic substances may cause clouding to the system. Soluble amphiphilic systems produce Gibbs monolayer at the air/water interface; insoluble amphiphiles form Langmuir monolayers.A documentary of the above aspects will be herein presented and discussed. We mention that this article is neither an original research article nor a review article. This is a mixture of the two: a documentary of both original research and some review of our works presented in memory of Prof. Milton Rosen.
