文摘

Macroporous materials comprising DNA were fabricated with the colloidal crystal template. First, DNA and diazoresin(DR) molecules are fully filled into the voids of a colloidal crystal template. After thermal treatment and removalof the colloids, DNA porous materials with highly ordered structure were obtained. In the process of thermal treatmentthe cross-linking reaction takes place between DR and DNA, which plays an important role for sustaining the porousframework. The DNA porous materials will turn into a fluorescent DNA/dye composite after staining with Hoechst33258 (Hoe), a characteristic fluorescent dye for DNA. This kind of composite DNA porous material may havepotential applications in optical devices.
