TEM pictures of PDAC cells trated with PEG–TiO₂ NPs or Kv 11.1-Mab-PEG–TiO₂ NPs: a, c Panc-1 treated with PEG–TiO₂ NPs (0.1 %). b MIAPaCa-2 treated with Kv 11.1-Mab-PEG–TiO₂ NPs (0.1 %); d Panc-1 treated with Kv 11.1-Mab-PEG–TiO₂ NPs (0.1 %); TEM was performed after exposure for 48 h to either PEG–TiO₂ or Kv 11.1-Mab-PEG–TiO₂ NPs. Scale bars are reported on the bottom left of each panel
