title: DNA liquid-crystalline gel as adsorbent of carcinogenic agent.
abstract: DNA liquid crystalline gel (LCG) has been newly prepared by a dialysis of concentrated DNA solutions into concentrated metal cation solutions. The condition for forming DNA LCG is examined by means of the insolubilization reaction. The shrinking ratio and the ratio of the thickness of LCG layer, delta, and the diameter of the dialysis tube, d0, do not depend on d0. The adsorption of one of carcinogenic agents, acridine orange is demonstrated. From the experimental results, the mechanism for forming DNALCG is discussed.
