Table 2.
Cumulative concentration of Ag (μg cm−2) in the cell culture (n = 1) and control experiment (n = 3) with a comparison of the values estimated by difference with the sum of the direct measurements in the MTT and dimethyl sulfoxide in isopropanol (iDMSO) fractions. TMAH: tetramethylammonium hydroxide.
