Morphological analysis of Zebrafish embryos exposed to 50 µg/ml of ZnO nanoparticles at different hour post fertilization (hpf). Significant accumulation of Bulk ZnO and nanoparticles were observed at 24hpf. 10 h ZnO nanoparticles exposed embryos showed acute effect with pericardial edema and notochord bending.
