Fig. 6From: The agglomeration state of nanoparticles can influence the mechanism of their cellular internalisationColocalisation of Rubipy-SiO2 NPs with clathrin. After 3 h exposure to Rubipy-SiO2 NPs the cells were fixed and incubated with anti-clathrin. The images of different channels were merged and the colocalisation of signal from channel Cy3 (Rubipy-SiO2 NPs, shown in red) and of signal from channel Cy5 (secondary antibodies, shown in green) obtained by ImageJ is shown in yellow Back to article page
