  1. The ZnO-NP suspension (50 % in H2O, average mean size 35 nm, < 100 nm (DLS)) was obtained from Sigma and characterized in H2O as well as in cell culture medium (CCM; RPMI + 10 % FCS). Zeta potentials were not determined (n.d.) in PBS or CCM
  2. aDLS: prior to nebulization in NaCl solution; TEM: after nebulization
