Protein microarrays on GO coatings. (A) Bright field and corresponding fluorescence image of a 729 features fibronectin microarray (9 × 9 feature subunits in a 9 × 9 array over an area of 1260 × 1260 µm2). (B) Subset of the microarray in (A). (C) Small-area 3 × 3 array of similar subunits in bright field and in fluorescence. All images were taken prior to washing step (to obtain visibility in bright field), scale bars equal 100 µm.
