A) & B) The images show well preserved cells. Cell organelles, cell nucleus and membranes are clearly visible. Scale bars 500 nm. C) Here, a vesicle filled with NPs is shown. Scale bar 100 nm D), E) and F) Accumulations of NPs in the cytoplasm. Scale bars: D) 100 nm, E) 100 nm and F) 500 nm. In all images the contrast and brightness was rescaled in order to improve the visualization of the cell organelles.
