Abstract
Relevant parameters for non-covalent protein functionalization of carbon nanotubes are
explored. Multiwalled carbon nanotubes are carboxylated and functionalized with
metalloproteins. Using atomic force microscopy (AFM) we quantitatively determine that
coverage with nitrogen-doped multiwalled carbon nanotubes is superior compared to coverage
with un-doped multiwalled carbon nanotubes, due to enhanced carboxylation. Conformational
analysis using a combination of AFM, antibody binding assays, circular dichroism and
UV–visible spectroscopy demonstrates that the metalloproteins retain their native structure
when adsorbed to nitrogen-doped multiwalled carbon nanotubes irrespective of their size,
charge or folding motif.
