Utilization of DNA as functional materials: preparation of filters containing DNA insolubilized with alginic acid gel.
Thin films composed of DNA and alginic acid were prepared by casting their mixed solution on glass plate followed by coagulation with aqueous solution of calcium chloride. DNA could be conveniently insolubilized by this method. DNA in the films adsorbed intercalating materials, such as ethidium bromide. This phenomenon was successfully applied to the preparation of filters for the selective removal or accumulation of harmful intercalating pollutants.
