amphiphile was studied by fluorescence microscopy (FM). The unfolding of DNA molecules
previously compacted with cationic surfactant was shown to be dependent on the anionic
surfactant chain length; lower amounts of a longer-chain surfactant were needed to release
DNA into solution. However, we observed no dependence on the hydrophobicity of the
compacting agent. The structures of the aggregates formed by the two surfactants, after the …
