Exploring a Nanotube Dispersion Mechanism with Gold-Labeled Proteins via Cryo-TEM Imaging Academic Article uri icon

abstract

  • Single-walled carbon nanotubes (SWNTs) possess unique electrical, mechanical, and optical properties, and hence have been implemented in applications ranging from nano- ACHTUNGTRENNUNGelectronics [1–3] through biosensors [4] to drug delivery.[5] Asproduced SWNTs are bundled due to strong van der Waals interactions. Therefore, substantial efforts have been devoted to dispersing and debundling SWNTs. Two main pathways for dispersing and exfoliating nanotubes (NTs) are covalently grafting the dispersing molecule onto the NT surface (functionalization),[6] or noncovalently adsorbing it around the NT surface.[7] We adopted the latter pathway since it is not expected to perturb the sp2 graphitic hybridization of the NTs, nor consequently, their electromechanical properties. While the noncovalent dispersion and exfoliation of SWNTs with surfactant,[8 …
