Additional file 6: of Surface PEGylation suppresses pulmonary effects of CuO in allergen-induced lung inflammation

Figure S2. Example transmission electron microscopy images of engineered CuO nanoparticles in 100 mg l− 1 Milli-Q water showing, (A) uncoated CuO core, (B) CuO-COOH, (C) CuO-NH4+ and, (D) CuO-PEG NPs. The respective Nanosight graphs show the particle distribution (bin sizes are hydrodynamic diameter) of the nanomaterials in 100 mg l− 1 Milli-Q water solutions. From Besinis and Handy, unpublished.
