Morphological aspects of human melanoma cells–A375 nuclei treated with concentration of 500 µg/mL wormwood leaves (WL) and wormwood stems (WS) extracts and different Fe₂O₃ NPs obtained from these extracts (WL 1_Fe₂O₃ NPs; WL 2_Fe₂O₃ NPs, respectively WS 1_Fe₂O₃ NPs; WS 2_Fe₂O₃ NPs) for an interval of 72h. The scale bars represent 20 μm. Fe₂O₃ NPs that are either attached or embedded in the cells nuclei are marked with yellow arrows, while the red circles highlight the apoptotic markers.
