In vitro toxicity of inorganic NPs on patient derived GBM cells. A GIN 28, and B GCE 28 were incubated with increasing concentration of GNPs, SiO2 and ZnO NPs for 4 hours, before changing the media containing the NPs with fresh media. Metabolic activity was determined 48 hours after changing the media, the experiment was run in triplicate, and fluorescence at 590 nm is expressed as % of control (no NPs). Results are expressed as the mean ± S.D. *P < 0.05; **P < 0.01; ***P < 0.001; and ****P < 0.0001 obtained using 2-way ANOVA with a Tukey post-test
