1. A method for producing a composite of enzyme and carbon structure, comprising:

  • (1) dispersing elongated carbon structures in an aqueous enzyme-solution comprising an enzyme so that the enzyme molecules adsorb on a surface of the carbon structures, wherein the surface of the carbon structures is not modified to form functional groups capable of forming covalent bonds with the enzyme molecules;

    (2) adding a precipitant to the enzyme solution to cause the enzyme molecules to precipitate and to deposit on the carbon structure; and

    (3) adding a cross-linker to cross-link the precipitated enzyme molecules, wherein the cross-linked enzyme molecules surround the carbon structures, and wherein there is no covalent bonding between the carbon structures and the enzyme molecules.
