Calcium measurements. Calcium transients in Ag-np treated U251 and IMR-90 cells: Cells were stained with calcium binding fluorophore and subsequently activated with Ag-np (A). Data obtained from experiments where the U251 cells were treated with Ag-np for 4 hours and then stained with the dye (B). Graph denotes the calcium concentrations in Ag-np treated IMR-90 cells at 4, 24 and 48 hours. (C) U251 cells treated with Ag-np. * p < 0.05 (n = 4).
