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

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

Quaternary ammonium compounds (QAC) constitute a family of widely used chemical substances. The QAC benzalkonium chloride (BAC) has caused bronchoconstriction in human beings by poorly understood mechanisms and lung damage at high concentration as shown in a single rat study.

The interaction of DNA with monolayers of the cationic lipid dimethyldioctadecylammonium bromide, with/without 50 mol % of a neutral "helper" lipid, either dioleoylphosphatidylethanolamine or cholesterol, has been studied using specular neutron reflection, surface pressure-area isotherms, and Brewster angle microscopy.
