Abstract
The structural changes of the didodecyldimethylammonium bromide (DDAB) vesicular bilayers after γ-irradiation and under conditions where mainly OH radicals are present are reported. Alterations of the vesicular structure, such as polarity and fluidity, were detected after a dose of 0.65 kGy. A higher dose of ~ 14 kGy cause important damage to the well organized molecular structure and this is manifested by an important augmentation of the fluidity and polarity of the Stern region of the aggregates. Increased water penetration into the bilayer of the vesicle is probably the reason for these changes and electron micrographs support this hypothesis.
