Fig. 13. SEM imaging of C. neoformans: (a) Regular fungal cells (C. neoformans) grown without the RGO-NiO, RGO-AgO, and RGO-ZnO nanocomposites; (b) abnormal, deformed and irregular fungal cells due to complete lysis following RGO-NiO treatment; (c) fully-irregular and deformed fungal cells due to RGO-AgO treatment, presenting the complete lysis of C. neoformans cells; (d) malformed fungal cells after treatment with the synthesized RGO-ZnO nanocomposite.
