“…Interestingly, the conformation of these residues over the CNT surface reveal a surfactant-like approach, where contact points are represented by the long alkyl chains these residues have in common, while the polar or charged moieties point towards the solvent (Fig. 134 They demonstrated that the solubilizing effect of milk is ascribable to its proteinic part and in particular to the b-lactoglobulin, that presents a narrow crevice (site A, Fig. The nature of this interaction was further characterized by DFT calculations (M06/6-31G*), which unambiguously attested the lack of polarization effects, confirming the pure hydrophobic nature of this binding.…”

Interfacing proteins with graphitic nanomaterials: from spontaneous attraction to tailored assemblies

This critical review aims at giving insights on the spontaneous tendency of proteins and their constitutive parts to adsorb on graphitic nanomaterials (GNMs) through non-covalent interactions occurring at their interfaces. Specifically, it focuses on the theoretical and experimental studies carried out to comprehend in depth the forces ruling the adsorption processes of proteins on fullerene, carbon nanotubes and graphene. In a systematic way the reader is guided through the most recent and representative examples describing at the atomistic level of detail the structural modalities and the chemico-physical principles through which amino acids, polypeptides and folded proteins interact with GNMs' surface, thereby taking into consideration the mutual effects of both protein structural complexity and nanomaterial topology. Based on their chemical and structural features, the study and understanding of the protein-nanomaterial interfaces can be exploited in the view of design and control the spontaneous formation of biologically-active hybrid materials for the development of new tailored applications in the field of sensing, nanomedicine and biochemistry.

“…The efficiency in obtaining high concentrations of CNT suspension is vastly sensitive to the dispersion parameters, like the initial concentrations of CNTs and the chosen dispersant, the composition [112,113], diameter and the chirality [114] of the initial pristine material, sonication power and sonication time [115] interval. Environmental factors like pH [116] and temperature [117] also affect the quality of the suspension.…”

Enzymatic ‘stripping’ and degradation of PEGylated carbon nanotubes

Single-walled carbon nanotubes (SWCNTs) coated or functionalized with PEG chains of different molecular weight were assessed for their propensity to undergo biodegradation under in vitro conditions using recombinant myeloperoxidase (MPO) or ex vivo using freshly isolated primary human neutrophils. Our findings suggest that under natural conditions, a combined process of 'stripping' (i.e., defunctionalization) and biodegradation of PEG-SWCNTs might occur and that PEG-SWCNTs are a promising--and degradable--nanomedicine vector.
