Effect of PBS-citrate (control) (A, B), TiO2 (C, D) and ZnO (E, F) agglomerated engineered nanoparticles on washed human erythrocytes as observed by scanning electron microscopy. Agglomerated engineered nanoparticles were suspended in phosphate buffer saline. Arrows point to very large agglomerates of nanoparticles.
