Summary

We developed a hybrid method to attach single-stranded DNA to multi-walled carbon nanotubes using surfactants. DNA wrapping on these nanotubes depends on their diameter, unlike single-walled carbon nanotubes.

Main Results:

  • Successful formation of hybrid complexes of MWCNTs decorated with ssDNA.
  • Demonstration of a diameter-dependent wrapping of nucleic acids around MWCNTs.
  • Observation that this behavior differs from single-walled carbon nanotubes.

Conclusions:

  • The developed hybrid approach enables non-covalent functionalization of MWCNTs with ssDNA.
  • MWCNT diameter is a critical factor influencing the efficiency and mode of DNA wrapping.
  • This finding provides insights into tailoring nanomaterial-biomolecule interactions.
