Comparison of cell adhesion on GO coating and control. (A) Bright field image of 3T3 cells on a protein microarray spotted on a GO coating. Scale bar equals 100 µm. (B) Corresponding fluorescence image of stained cell nuclei. Scale bar equals 100 µm. (C) Close-up of a single pattern subunit in bright field, and single fluorescence channels for fibronectin (green) and cell nuclei (blue) signal. Scale bars equal 50 µm.
