Chemically controlling carbon nanotubes' (CNTs) assembly could lead to new biomaterials, say scientists in Italy. Maurizio Prato and Mildred Quintana at the University of Trieste have developed a chemical method to manipulate CNTs using hydrogen bonding networks. Normally carbon nanotubes assemble in tight bundles that are difficult to disperse and manipulate, says Prato. 'Through intermolecular interactions, carbon nanotubes can be self-assembled into many different structures' he explains.
