Preparation of protein arrays on graphene oxide substrates. (A) Scheme of microchannel cantilever spotting (µCS) technique, used for spotting fibronectin onto graphene oxide substrates. (B) Steps in the preparation of the protein arrays: a clean glass substrate is silanized with GPTMS. Next, Graphene oxide (GO) flakes are deposited by spin coating and fibronectin containing ink is spotted by µCS. After washing away excess ink, fibronectin spots remain on the substrate. (C) Fibronectin ink droplet microarray under polarized light after spotting (pre-wash).
