Deposition of collagen I on patterns generated on various substrates. POEGMA brushes were patterned on glass (A), APTS-coated glass (B), LBL-coated glass (C) and gold and substrates were subsequently incubated in collagen I solutions, immuno-stained and imaged via fluorescence microscopy. Height profiles were taken along the dashed lines. Scale bar: 100 μm.
