Schematic of micropatterning on PDMS substrates. (A) Benzophenone diffusion on to PDMS surface. (B) A PEG-DA layer is initially spin coated on the surface (shown to different scale for clarity). (C) Exposure of UV through bright field mask. (D) Hydrophilic hydrogel micropatterns constructed on the substrate for cells.
