Table 1 Hydrodynamic diameter, zeta potential and PdI values after dispersion of 50 μg/ml Cu of CuO NMs in complete cell culture medium

From: Impact of copper oxide nanomaterials on differentiated and undifferentiated Caco-2 intestinal epithelial cells; assessment of cytotoxicity, barrier integrity, cytokine production and nanomaterial penetration

Time (h) Hydrodynamic diameter (nm) Zeta Potential PdI
0 157.37 ± 29.44* −7.38 ± 0.59 0.6 ± 0.07*
24 24.01 ± 0.56 −7.29 ± 0.05 0.42 ± 0.1
  1. CuO NMs were dispersed in 2% FCS in water, sonicated and then diluted in complete cell culture medium and the hydrodynamic diameter, zeta potential and PdI were measured immediately (0 h) or following incubation at 37 °C, 5%, CO2 and 95% humidity for 24 h. Data expressed as Mean ± SEM (n = 3). Asterisk (*) represents significance when incubation at time point 0 and 24 h are compared P < 0.05
