In this study, spring dextrin (SD) has been noncovalently wrapped onto single-wall carbon nanotubes (SWNTs) to explain the number of glucose residues per turn larger than eight. Differential scanning calorimetry (DSC), FR-IR and Raman spectroscopy demonstrated that SD formed supramolecular complex with SWNTs. Furthermore, Atomic force microscope (AFM) micrograph indicated that SD wrap around SWNTs into helical superstructures. Finally, molecular dynamic simulation suggested that the space of helix cavity changed with different diameter of SWNTs, and SD wrapped around SWNTs (1 nm, 1.5 nm and 2 nm) were 11, 14 and 17 glucose units per turn, respectively.
