Figure 6. Both Au- and AgNP exposure increased the GFAP-expression in HNPCs.

Figure 6

Exposure to the NPs resulted in longer, more perforated, and partly thicker GFAP+ processes, while nanoparticle-size or particles/cell did not have any effect the GFAP-expression. Au 20∶800, gold 20 nm and 800 particles/cell; Au 80∶800, gold 80 nm and 800 particles/cell; Ag 20∶800, silver 20 nm and 800 particles/cell; Ag 80∶800, silver 80 nm and 800 particles/cell; AgNO3 1.0, silver nitrate 1.0 mg/ml. Scale bars equal 107 µm.
