Abstract
Obtaining the stable dispersion of single-walled carbon nanotubes is vital for realizing their practical applications. In our work, soy protein isolate and keratin were utilized to disperse SWNTs. Investigations demonstrated that the stretched β-sheet and β-turn structures of proteins were more effective in dispersing SWNTs than the spiral α-helix structure. The secondary structures of proteins were characterized by the deconvolved Fourier transform infrared spectroscopy and the circle dichroism spectra. The biocompatibility of proteins helps in advancing the applications of SWNTs in biomedicine and biotechnology.
