In order to expand biotechnological applications of carbon nanotubes (CNTs), the ability of biological molecules to interact with CNTs is studied. We report the formation of stable aqueous polydisperse colloidal systems of SWNTs and MWNTs non-covalently functionalized with several biomolecules — double-stranded DNA, deoxyribonucleotide triphosphates, adenosine triphosphate sodium salt, bovine serum albumin, vitreous body extract proteins and sodium humate. The results of Raman spectroscopy, transmission electron and atomic-force microscopies of functionalized CNTs demonstrating morphological and structural changes in CNTs caused by the functionalization are shown. Mechanisms of non-covalent biomolecules-CNTs interactions are discussed.
