Vesicle Origami and the Influence of Cholesterol on Lipid Packing.
TLDR
The artificial phospholipid Pad-PC-Pad was analyzed in 2D (monolayers at the air/water interface) and 3D (aqueous lipid dispersions) systems and found that cholesterol has an ordering effect on liquid-expanded phases and disorders condensed phases.
Lysine-based amino-functionalized lipids for gene transfection: the protonation state in monolayers at the air-liquid interface.
TLDR
Newly synthesized peptide-mimic lysine-based amino-functionalized lipids have been investigated in 2D models as monolayers at the air-liquid interface and it is found that the protonation degree depends linearly on the packing density of the lipid monolayer.
DNA Delivery Systems Based on Peptide-Mimicking Cationic Lipids—The Effect of the Co-Lipid on the Structure and DNA Binding Capacity
TLDR
The correlation of the observed structures with the transfection efficiency and serum stability indicates that OO4/DOPE 1:3 lipoplexes with a DNA-containing cubic phase encapsulated in multilamellar structures seem to be most promising.
Composites of malonic acid diamides and phospholipids – Structural parameters for optimal transfection efficiency in A549 cells
TLDR
The lipid mixtures with the fluid cationic lipid OH4 and DOPE have shown comparable transfection efficiency with Lipofectamine 2000® and the huge influence of the helper lipid on the transfections efficiency is demonstrated.
Structures of malonic acid diamide/phospholipid composites and their lipoplexes.
TLDR
Self-assembly process of cationic lipid formulations in the presence and absence of DNA was investigated with respect to binary lipid mixtures suitable as polynucleotide carrier systems, indicating differences in the binding strength between DNA and the lipid composition.
Lysine-based amino-functionalized lipids for gene transfection: the influence of the chain composition on 2D properties.
TLDR
This work investigated the lipids as Langmuir monolayers at the air-water-interface in the absence and presence of calf thymus DNA applying different techniques such as infrared reflection absorption spectroscopy (IRRAS) and grazing incidence X-ray diffraction (GIXD).
Structure of Langmuir Monolayers of Perfluorinated Fatty Acids: Evidence of a New 2D Smectic C Phase
TLDR
Grazing Incidence X-ray Diffraction measurements exhibit two diffraction peaks on the transition plateau, one of which is the signature of the hexagonal structure of the LC phase, the second one is associated to the low-density fluid phase and is thus more ordered than expected for a 2D gas or a typical fluid phase.
Lysine-based amino-functionalized lipids for gene transfection: 3D phase behaviour and transfection performance.
TLDR
Interestingly, TT10 and OT10 form cubic lipoplexes, whereas OO10 complexes the DNA sandwich-like between lipid bilayers in a lamellar lipoplex, Surprisingly, the latter is the most effectivelipoplex.
Protein Nanopore Membranes Prepared by a Simple Langmuir-Schaefer Approach.
TLDR
A simple procedure is described to prepare ultrathin membranes based on protein nanopores, which exhibit excellent water permeance, two orders of magnitude superior to comparable, industrially applied membranes.
