a HRTEM image of an iron oxide NP in an FCR-1 cell. b EELS spectrum measured at Fe L2,3 edges of the iron oxide NP. The spectrum is compared with the spectra of reference Fe3O4 and Fe2O3. c HRTEM analysis of the Fe3O4 NP obtained along the [110] zone axis and the fast Fourier transform (FFT) pattern. (002), (1-1-1), (1-11) and (2-20) crystal faces are indicated by red, green, yellow and orange solid circles, respectively. Box plots of length (d), width (e) and shape factor (f) of Fe3O4 NPs in FCR-1 cells grown under heterotrophic conditions. The length, width and shape factor of each box represented the central range covering 50% of the distribution, the horizontal line represented median and the bar ends corresponded to the maximum and minimum values of each distribution.
