The determination of CNC dimensions is complicated due to specific limitations of the different analytical methods used. On the one hand, in the case of TEM images for unstained CNC, the main drawbacks are limited contrast and sample damage from the electron beam. On the other hand, the tip/sample broadening represents the main limitation for AFM, resulting in an overestimation of CNC dimensions. Thus, both TEM and AFM were performed in order to have a detailed characterization of the dimensions of the individual crystallites. Thus, TEM images of negatively stained preparations were recorded in order to measure the length and width of the particle with a better precision, while AFM images allowed to measure the CNC thickness. Moreover, aggregation, bundling, network formation and overlapping of individual CNCs also can make accurate dimension measurements difficult with both techniques
