Improvements in transfection efficiency are required in order to make the goal of cellular gene delivery by non-viral vectors realizable. Novel derivatives of gemini surfactants having dissymmetric tail groups have been designed specifically as a means to improve DNA transfection; the micelle and interfacial properties are reported herein. The effect of these substitutions on the aggregation properties of the gemini surfactants is discussed in the context of results for the m m gemini series, previously reported in the literature. Phytanyl substitution results in lower cmc and higher micelle ionization. In addition, the phytanyl substituted gemini surfactants form vesicles at room temperature.

Synthesis and properties of novel gemini surfactant with short spacer

China E-mail: luyiqiao hotmail. China E-mail: zl The adsorption and wetting on quartz surfaces by aqueous solutions of xylyl-substituted biquaternary ammonium salt gemini surfactants with different spacer groups C 3 and C 6 , have been investigated. The obtained results show that C 3 and C 6 have similar adsorption behavior on quartz surfaces. Before critical micelle concentration cmc is reached, the contact angles of gemini surfactants slowly increase with the increasing concentration, and the adsorption amount at the water—air interface is almost the same as those at a quartz—water interface.

Cationic gemini surfactant dimethylene-1,2-bis dodecyldiethylammonium bromide , referred to as C 12 C 2 C 12 Et was synthesized, and its surface property and aggregation behavior in aqueous solution were studied. Spherical and elongated micelles were formed in the aqueous solution of this gemini surfactant, and the spherical micelles were absolutely dominant compared to the elongated micelles at our studied concentration quantitatively.

By Bogumil E. Brycki, Iwona H. Gemini cationic surfactants are compounds which are composed of two hydrophilic head groups and two hydrophobic tails linked by a spacer at the head groups or closed to them. The spacer can be either hydrophobic or hydrophilic.
