“…glucose oxidase [9]. Azamian et al [10] observed adsorption of ferritin protein onto SWNTs which resulted in the solubilisation of SWNTs in water. In contrast, Dai and co-workers reported that incubating SWNTs grown on a TEM grid in aqueous ferritin solution resulted in no observable adsorption [11].…”

“…The functionalization of CNTs with biomolecules can be realized by both noncovalent-and covalent-based modification, and several biomolecules can also become adsorbed directly to CNTs noncovalently. In particular, antibodies (60), enzymes (61), and peptides (62) can bind nonspecifically to the exterior surface of CNTs, whereas oligonucleotides can bind to the surface as well as the open cavity space of CNTs. DNA-CNT interactions in water are suggested to result from DNA base-stacking at the CNT surface, with the hydrophilic sugarphosphate backbone oriented outward toward the aqueous medium (63).…”

Bioconjugation of carbon nanotubes (CNTs) with biomolecules promises exciting applications such as biosensing, nanobiocomposite formulation, design of drug vector systems, and probing protein interactions. Pristine CNTs, however, are virtually water-insoluble and difficult to evenly disperse in a liquid matrix. Therefore, it is necessary to attach molecules or functional groups to their sidewalls to enable bioconjugation. Both noncovalent and covalent procedures can be used to conjugate CNTs with a target biomolecule for a specific bioapplication. This chapter presents a few selected protocols that can be performed at any wet chemistry laboratory to purify and biofunctionalize CNTs. The preparation of CNTs modified with metallic nanoparticles, especially gold, is also described since biomolecules can bind and self-organize on the surfaces of such metal-decorated CNTs.
