Figure 2From: Genotoxicity and molecular response of silver nanoparticle (NP)-based hydrogelCell morphological changes. The cells were post-exposed with silver-NP-hydrogel (40 mg/ml) and Hydrogel (40 mg/ml) as the study groups and with no treatment as a control for 24 h (up-panel, X 200) and 48 h (bottom-panel, X 400). The changes of cell morphology were visualized by light microscopy.Back to article page
