Decylammonium bromide

The application of a 11-ferrocenylundecyl-ammonium bromide/hexa-decylammonium bromide surfactant mixture as structure-directing agent resulted in a lamellar mesostructured silica film, which showed electronic conductivity due to electron transport in the ferrocenyl chains. Lyotropic lithium triflate-silicate liquid crystals have been utilized as supramolecular templates in the synthesis of ionically conducting nanocomposite films. ... 

FIGURE 6.8 Transfection efficiency (quantified as relative light units [RLU]/mg protein) of six different SLN formulations (Co DDAB 4% Compritol ATO 888, 1% dimethyldiocta-decylammonium bromide = DDAB Co EQ 4% Compritol, 1% N,N-di-(P-stearoylethyl)-N,N-dimethyl-ammonium chloride = EQ Co DOTAP 4% Compritol, 1% N-[l-(2,3-dioleoy-loxy)propyl]-N,N,N-trimethylammonium chloride = DOTAP Cp DDAB 4% cetyl pahnitate, 1% DDAB Cp EQ 4% cetyl pahnitate, 1% EQ Cp DOTAP 4% cetyl palmitate, 1% DOTAP) all formulations were stabilized with 2% [7 3] Tween 80 Span 85). The experiments were performed on Cos-1 cells (African green monkey kidney). The transfection efficiency of naked plasmid (DNA alone) served as control. All tested SLN-DNA complexes showed a statistically significant increase of transfection activity compared to naked plasmid. Cp DOTAP was 10 times more potent then the other formulations. 

Examples of other frequently used surfactants that able to form reversed micelles without the addition of cosurfactants are didodecyldimethyl ammonium bromide [17], do-decylammonium propionate, benzyldimethylhexadecyl ammonium chloride [18], lecithin [19], tetraethyleneglycol monododecylether (C12E4) [20], decaglycerol dioleate [21], do-decylpyridinium iodide [22], and sodium bis(2-ethylhexyl) phosphate [23],...
