Effects of the Absorption Behaviour of ZnO Nanoparticles on Cytotoxicity Measurements

Figure 7

Morphological changes of A549 and SH-SY5Y cell lines after 96 h incubation in Z1 (85.7 nm) nanoparticles: (a) and (b), control cells in regular cell culture (no nanoparticles); (c) and (d), cell lines treated with 1 mM of Z1 nanoparticles; (e) and (f), cell lines treated with 5 mM of Z1; (g) and (h), cell lines treated with 5 mM of Z1 followed by disposing ZnO.

(a) SH-SY5Y—(control)

(b) A549— (control)

(c) SH-SY5Y—1 mM/96 h

(d) A549—1 mM / 96 h

(e) SH-SY5Y—5 mM/96 h

(f) A549—5 mM/96 h

(g) SH-SY5Y—5 mM/96 h (ZnO disposed)

(h) A549—5 mM/96 h (ZnO disposed)
