Colon 26 cellular morphology after incubation with pristine and aminated GO nanoparticles for 24 hours. (a) Phase-contrast light microscopic micrographs of Colon 26 cells incubated for 24 hours in the presence of GO and GO-NH₂ nanoparticles at different concentrations. Magnification 10x; bar 100 μm; (b) phase-contrast light microscopic micrographs of Colon 26 cells incubated for 24 hours in the presence of GO and GO-NH₂ nanoparticles at different concentrations. Cells were stained with neutral red. Magnification 63x; bar 10 μm, (c) FACS data representing relative cellular size and cell granularity of Colon 26 cells after incubation with different concentrations of pristine and aminated GO—cellular morphology according to FSC and SSC light scattering profiles of each probe. Two repetitions of the experiment are done, and results are presented as a table.
