The MTT assay was performed to determine the cytotoxicity as a function of concentrations of: (A) PYRRO/NO; (B) 45 mol% AHAP3/NO, and (C) 75 mol% MAP3/NO silica nanoparticles on the A2780 ovarian carcinoma cell line: ●, controls (i.e. pyrrolidine, non-diazeniumdiolated AHAP3 and MAP3 silica nanoparticles) and ○, NO releasing. The results were plotted as cell viability, which was measured by absorbance at a wavelength of 560 nm (y-axis) versus drug concentration (x-axis). Amount of NO released was calculated from the values listed in Table 1.
