This study demonstrates a simple scheme to fabricate topographically and chemically micropatterned all-polymer surfaces. A dual-use mask results in inherently self-aligned patterns in a single lithographic step. This process is used to create flat surfaces with spatially regular variations in physical and chemical properties, as well as microwells (shown here, scale bar = 5 µm) whose depth can be actuated with a water stimulus.
