Fig. 8. SEM and corresponding EDX elemental analysis of E. coli. [A] Normal bacterial cell without treatment with 100 kGy gamma-irradiated CoxNi1−xFe2O4/SiO2/TiO2; x = 0.9 nanocomposite. [B] The depressed and deformed bacterial cell after treatment with 100 kGy gamma-irradiated CoxNi1−xFe2O4; x = 0.9/SiO2/TiO2 nanocomposite (yellow square represents complete lysis of E. coli cells). [C] The corresponding EDX elemental analysis of the treated E. coli cell, confirming the cellular internalization of the 100 kGy gamma-irradiated CoxNi1−xFe2O4; x = 0.9/SiO2/TiO2 nanocomposite.
