Figure 1

Sketch of the functionalization of flat polyacrylamide hydrogel with collagen (FPC) and cell culture application. Parylene C is placed on glass coverslips (a), treated with oxygen plasma (b) and uniformly coated with collagen (c). PAm pre-polymer solution is gently pipetted on activated glass coverslips and Parylene C mask is put in contact with the solution (e). After hydrogel polymerisation, the mask is removed (f), and FPC samples are stored in PBS (g). In (h) and (i) top and section views of FPC and GPC are shown with cells randomly distributed in FPC and aligned in GPC.
