Figure 1From: Carbon black and titanium dioxide nanoparticles elicit distinct apoptotic pathways in bronchial epithelial cellsSize distributions of NPs in suspension. Dynamic light scattering (DLS) analysis of CB and TiO2 NPs after suspending in water, PBS or DMEM-F12 cell culture media was performed to determine size distributions and hydrodynamic diameters of NPs.Back to article page
