Vesicle formation from dimeric ion-paired amphiphiles. Control over vesicular thermotropic and ion-transport properties as a function of intra-amphiphilic headgroup separation
Santanu Bhattacharya,Soma De +1 more
TL;DR: All lipid vesicles entrap riboflavin and that generally the resistance to OH- permeation decreases with the increase in m value, which means that membrane propel-ties can be modulated by spacer chain length variation of the ion-paired amphiphiles.

Small-Angle Neutron Scattering Studies of Different Mixed Micelles Composed of Dimeric and Monomeric Cationic Surfactants
TL;DR: In this article, small-angle neutron scattering (SANS) cross sections from different mixed micelles composed of CTAB and Br-, n-C16H33N+Me2−(CH2)mN+me2−n-C 16H33, Br- (16-m-16, 2Br-, where m = 3, 5, and 10), in aqueous media (D2O).

Synthesis and vesicle formation from dimeric pseudoglyceryl lipids with (CH2)(m) spacers: pronounced m-value dependence of thermal properties, vesicle fusion, and cholesterol complexation
Santanu Bhattacharya,Soma De +1 more
TL;DR: Eight new dimeric lipids, in which the two Me2N+ ion headgroups are separated by a variable number of polymethylene units [-(CH2)(m)-], have been synthesized and it was revealed that these lipids organize in three different ways depending on the m value.

Synthesis and vesicle formation from novel pseudoglyceryl dimeric lipids. Evidence of formation of widely different membrane organizations with exceptional thermotropic properties
TL;DR: Eight new bis-cationic dimeric lipids 2a–h have been synthesized; TEM of their aqueous dispersions confirmed the vesicle formation and from the thermal, spectroscopic, DLS and XRD studies it has been revealed that they form three different kinds of membranous aggregate depending on the m-value.

Synthesis and vesicle formation from hybrid bolaphile/ amphiphile ion-pairs. evidence of membrane property modulation by molecular design
TL;DR: In this paper, four new hybrid ion-pairs were synthesized and electron microscopy indicated that each of these forms bilayer membranes upon dispersion in aqueous media.
