CARBON NANOTUBES MASSIVELY ENHANCE THE FIBRILLOGENESIS OF D76N (as can be observe in panel B of Figure 1)
It has been previously shown \cite{Linse_2007}, even though at pH 2.5, that nanoparticles enhance the rate of the protein fibrillation by decreasing the lag time of the nucleation. In the particular case of b2m, they found that NPs enhance the probability of appearance of a critical nucleus for nucleation of protein fibrils, with a strong relation between the shorter lag time (nucleation) and the nature of the particle surface.
