Photopatterning SAM substrates. A) A photochemical strategy for generating patterns of immobilized ligands onto an electrochemically active monolayer. UV illumination of the NVOC-protected hydroquinone through a photomask reveals the hydroquinone in select regions on the monolayer. Electrochemical oxidation of the hydroquinone monolayer to the quinine permits selective immobilization of ligands to the patterned surface. B) Representative fluorescent images of Swiss 3T3 Fibroblasts on various photo patterns of RGD ligands. Patterned cells were stained for actin (red), microtubules (green), and nuclei (blue).
