Thermal and structural behavior of dioctadecyldimethylammonium bromide dispersions studied by differential scanning calorimetry and X-ray scattering.

Eloi Feitosa et al.

PloS one, 7(9), e44702-e44702 (2012-09-13)

Dioctadecyldimethylammonium bromide (DODAB) is a double chain cationic lipid, which assembles as bilayer structures in aqueous solution. The precise structures formed depend on, e.g., lipid concentration and temperature. We here combine differential scanning calorimetry (DSC) and X-ray scattering (SAXS and

RNA and DNA association to zwitterionic and charged monolayers at the air-liquid interface.

Agnes Michanek et al.

Langmuir : the ACS journal of surfaces and colloids, 28(25), 9621-9633 (2012-05-26)

The objective of this work is to establish under which conditions short RNA molecules (similar to miRNA) associate with zwitterionic phospholipids and how this differs from the association with cationic surfactants. We study how the base pairing (i.e., single stranded

Spectroscopic studies on interactions between cholesterol-end capped polyethylene glycol and liposome.

Zhi Rao et al.

Colloids and surfaces. B, Biointerfaces, 97, 248-253 (2012-05-23)

In order to confirm that the cholesterol end groups of cholesterol-end capped polyethylene glycol really insert into the liposome bilayer and investigate how the incorporation affects the microenvironment of liposome bilayer, two kinds of molecular probes, namely Nile Red and
