Preparation of Nucleic Acid-Biopolymer Composites with Regular Structure

随后制备了含DNA的复合材料，以寻找由DNA结构引起的具有新功能的功能材料。DNA-胶原复合材料。(1)鲑鱼精子DNA-胶原复合体(2)质粒DNA-胶原复合体2。DNA合成聚合物复合材料。(1)DNA-聚丙烯酰胺复合材料(2)DNA-聚乙烯醇复合材料的互穿网络。DNA-金属复合材料。(1)DNA-Cu^&lt；2&gt；复合材料；采用溶胶-凝胶法制备DNA-二氧化硅复合体。具有离子导电性的DNA复合材料。这些含DNA的复合材料将有可能作为复杂的功能材料应用于各种领域，如医用聚合物、DNA结合材料的分离装置和离子导电材料。

Following DNA-containing composites were prepared to find the functional materials with novel functions caused by the DNA structure.1. DNA-collagen composites. (1)salmon sperm DNA-collagen composite (2) plasmid DNA-collagen composite2. DNA-synthetic polymer composites. (1)DNA-polyacrylmnide composite (2)interpenetrate network of DNA-polyvinyl alcohol composite.3. DNA-metal composites. (1)DNA-Cu^<2+> composite (2)DNA-Al^<3+> composite4. DNA-silica composite by sol-gel method.5. DNA composites with ion conductivity.These DNA-containing composites would have possibilities to be used in various fields as sophisticated functional materials such as medical polymers, separating devices for the DNA-binding materials and ion conductive materials.
