Toxicity of Silver Nanoparticles at the Air-Liquid Interface

Table 3

Number, surface area, and mass dose (median and 25th and 75th percentiles) of silver nanoparticles applied to cells as a function of diameter.

Diameter (nm)	Number; (# × 10^6 cm^−2); Median (25th, 75th)	Surface Area; (mm^2 cm^−2); Median (25th, 75th)	Mass; (ng cm^−2); Median (25th, 75th)
50	7.6 (4.0, 8.7)	0.06 (0.03, 0.07)	5 (3, 6)
75	5.5 (4.7, 6.5)	0.10 (0.08, 0.12)	13 (11, 15)
100	4.7 (3.9, 5.5)	0.15 (0.12, 0.17)	26 (22, 30)
