Light transmission images of a control cells and b D. radiodurans loaded with PtNPs during 12 h. Fluorescence images of c control cells and d D. radiodurans cells incubated with PtNPs for 12 h (the green dots correspond to the fluorescence signal of PtNPs). e Correspond to the merging of a and c images and f corresponds to the merging of b and d images. The scale bar is 5 μm
