将浓DNA溶液透析成浓金属阳离子溶液，制备了DNA液晶凝胶（LCG）。通过不溶反应考察了DNA LCG的形成条件。收缩比与LCG层厚度之比delta、透析管直径之比d0不依赖于d0。对一种致癌物吖啶橙进行了吸附实验。从实验结果出发，讨论了DNALCG的形成机理。
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.
