and low threshold values suggest that the DNA-lipid complexes are practical
candidates for thin-film dye lasers.
Another use of the DNA-lipid complex was reported by Wong and cowor-
kers [33]. The DNA molecule structural features can be imprinted into CdS
nanostructures by using self-assembled DNA-membrane templates. The ini-
tial application of the DNA-lipid multilamellar structure was the use as gene
carriers in gene therapy, and many reports [34-39] were published (Fig. 6b).
To prepare the DNA templates, anionic DNA was reacted with a mixture of
