  • Title: Three-dimensional self-assembly of graphene oxide and DNA into multifunctional hydrogels.
    Author: Xu Y, Wu Q, Sun Y, Bai H, Shi G.
    Journal: ACS Nano; 2010 Dec 28; 4(12):7358-62. PubMed ID: 21080682.
    Abstract:
    Graphene and its functionalized derivatives are unique and versatile building blocks for self-assembly to fabricate graphene-based functional materials with hierarchical microstructures. Here we report a strategy for three-dimensional self-assembly of graphene oxide sheets and DNA to form multifunctional hydrogels. The hydrogels possess high mechanical strength, environmental stability, and dye-loading capacity, and a exhibit self-healing property. This study provides a new insight for the assembly of functionalized graphene with other building blocks, especially biomolecules, which will help rational design and preparation of hierarchical graphene-based materials.
