Component analyses of intracellular iron oxide nanoparticles in MSR-1 wild type after the induction of ferric citrate for 15 min and 25 min by HRTEM. HRTEM analysis of intracellular iron oxide nanoparticles form samples, FFT analyses are shown below the corresponding HRTEM images. M, ε, and H subscripts shown in FFT pattern denote Fe3O4 (magnetite), ε-Fe2O3, and α-Fe2O3 (hematite) phases, respectively. The time shown beside the individual HRTEM image is the interval when the samples were taken out after the induction of ferric citrate. Yellow cycles are for eye guide
