Schematic of process for transferring protein pattern to collagen. A) The desired pattern is first created on a glass surface after which B) BS3 crosslinker solution and collagen are placed on the pattern and spread with a PDMS sheet. C) The gel is allowed to crosslink with the pattern and then peeled from the glass. The PDMS backing can be removed leaving a D) stand-alone collagen gel with a surface with patterned proteins.
