Cationic liposomes composed of dipalmitoylphosphatidylcholine (DPPC) and dipalmityldimethylammmonium bromide (DPAB) were prepared by the Bangham method and the effect of DPAB on the membrane properties was examined in terms of liposomal shape, particle size, trapping efficiency, surface potential and dispersibility. The dispersibility of the mixed DPPC/DPAB liposomes (the mole fraction of DPAB (XDPAB)>==0.05) was excellent and the dispersibility was maintained for 6 months, since the zeta… Expand

Stearylamine Changes the Liposomal Shape from MLVs to LUVs
The shape of mixed dipalmitoylphosphatidylcholine (DPPC)/stearylamine (SA) liposomes prepared by the Bangham method was examined using freeze-fracture electron microscopy. The shape of the mixedExpand
Molecular packing and lateral interactions of distearoylphosphatidylcholine with dihexadecyldimethylammonium bromide in Langmuir monolayers and vesicles.
The condensing effect and the increase of intermolecular attraction in mixed DSPC/DHDAB monolayers may be related to the stability enhancement of mixed vesicle composition as compared with the stability of pure component vesicles. Expand
Characterizing the structural transition of cationic DPPC liposomes from the approach of TEM, SAXS and AFM measurements.
It seems that the shape transition of DPPC liposomes results from such electrostatic interactions as well as packing geometry of the two components, and the large-unilamellar vesicles are formed for reducing the inter- and intra-firm repulsive forces. Expand
Effect of chain length on physicochemical properties and cytotoxicity of cationic vesicles composed of phosphatidylcholines and dialkyldimethylammonium bromides.
The morphological features (round shape, chromatin condensation and apoptosis bodies) and results of flow cytometry analysis confirmed the induction of apoptosis in HaCaT and SCC25 cells by cationic vesicles, suggesting that cytotoxicity is related to the zeta potential of the cationing vesicle.

Direct measurement of surface charge distribution in phase separating supported lipid bilayers.
The measured surface charge densities reveal that disordered domains formed by charged lipids are in fact not only impure, but also incorporate uncharged saturated lipids, which could present a limit for the formation of charged domains in lipid membranes. Expand

These phenomena were suggested to be related to the previously observed fact for the mixed DPPC/Ceramide 3 monolayers that Ceramide 3 interacts with DPPC in the liquid-expanded phase with consequent phase separation accompanied with domain formation. Expand
Formation and characterization of phosphatidylethanolamine/lysophosphatidylcholine mixed vesicles.
The lipid aggregates formed by adding lysophosphatidylcholine (lysoPC) solution to phosphatidylethanolamine (PE) dispersion were proved to be a vesicle system judged from the negatively stained electron micrographs and the latency of calcein fluorescence. Expand

DOTAP/DOPE and DC-Chol/DOPE lipoplexes for gene delivery: zeta potential measurements and electron spin resonance spectra.
ESR spectra showed that no major alteration took place after lipoplex formation and molecular packing remained substantially unchanged, and both zeta potential and ESR measurements were in favor of an external mode of packing of the lipoplexes. Expand

A substantial fraction of the aqueous phase is entrapped within the vesicles, encapsulating even large macromolecular assemblies with high efficiency, and has unique advantages for encapsulating valuable water-soluble materials such as drugs, proteins, nucleic acids, and other biochemical reagents.

Diffusion of univalent ions across the lamellae of swollen phospholipids.
It is found that as the surface charge of the lipid lamellae is increased, the amount of cation per μmle of lipid increases, and the phospholipid liquid crystalline structures appear to “bind” or “capture” cations. Expand
Correlation between structure and transfection efficiency: a study of DC-Chol--DOPE/DNA complexes.
The results show that DC-Chol--DOPE/DNA lipoplexes have a columnar inverted hexagonal structure, which is not influenced by the cationic liposome/DNA charge ratio, and it seems that the lipoplex structures have not any influence on transfection efficiency and toxicity in the experimental system.
