“…As can be observed in Table 3, any type of study involves the use of electron microscopy, mostly transmission electron microscopy (TEM) or scanning electron microscopy (SEM), but also dynamic light scattering (DLS), and microscopy-related techniques [e.g., atomic force microscopy (AFM)] to localize ENMs [27,36] as well as establish particle size [28,29,41], and size distribution [7,31,39,40].
