Characterization of Multiwalled Carbon Nanotubes Dispersing in Water and Association with Biological Effects
Figure 3
DLS analysis of as-received l-MWCNTs and the four oxidized l-MWCNTs dispersing in water, in which, (a) and (c) give average hydrodynamic diameters and Zeta potentials of as-received l-MWCNTs and the four kinds of oxidized l-MWCNTs dispersing in water and in the culture medium; (b) and (d) present DLS spectra of the four kinds of oxidized l-MWCNTs dispersing in water and in the culture medium, respectively.
