Figure 15.

KARPAS299 cell morphology assessment after 24 h of incubation with graphene family materials (GN, GO, and nGO) in comparison to the control group (C). Live images in bright field and phase contrast and after staining with May-Grünwald and Giemsa (MGG) method. All pictures in the main panel were taken under the same magnification (200×). Part of the presented picture for the GO group is additionally magnified for clearer visualization of the large, thick GO flake with a visible fold. These large and thick flakes were rarely visible in the culture.
