Carbon nanotubes are a novel nanomaterial based on carbon with salient properties. As these nanotubes are extremely hydrophobic and thus insoluble in water, it was a scientific challenge to bring them in contact with hydrophilic, water-soluble molecules such as proteins and enzymes. We have succeeded in developing several procedures to interact these materials with antipodal properties and, simultaneously, to make the carbon nanotubes soluble in water. Thus, for the first time, nanocomposites of carbon nanotubes and proteins have been synthesized. In this computer-assisted illustration, the colored molecular model of the enzyme glucose oxidase is wrapped around the single-walled carbon nanotube in the center. The colors of the protein model differentiate different segments of the molecule that are interacting with the carbon nanotube. These novel nanobiocomposites have very interesting properties and also high potential for biomedical and sensor applications. The novel experimental approach was published in the prestigious nanotechnology journal Small.
