Synthesis and spectroscopic characterization of single-wall carbon nanotubes wrapped by glycoconjugate polymer with bioactive sugars
A novel multivalent carbohydrate-CNT hybrid has been synthesized from SWNT and glycoconjugate polymer, carrying carbohydrate as pendant groups at side chain. Dispersion of SWNT in aqueous solution by using glycoconjugate polymer is achieved by sonication and ultracentrifugation. The multivalent carbohydrate-CNT hybrid is revealed to be photoluminescence active by near-infrared fluorescence spectroscopy. AFM measurements of the hybrid support not only the wrapping of SWNT by glycoconjugate polymer but also successful carbohydrate attachment of individual SWNT. (c) 2006 Elsevier B.V.
