Each value represents the mean of three separation determinations
appear to decrease. These results suggest that the organic solvent does not
damage the DNA double-stranded structure and the adsorption capacity for
the dioxins was maintained.
For environmental applications, hybridization of DNA with other poly-
mers is a recommendable approach for creating water-insoluble DNA ma-
