(a) Preparation scheme of the PVA-micropatterned surface. (b–d) Phase contrast micrographs of the photomask. (e–g) Phase contrast micrographs of the PVA-micropatterned polystyrene surface. Three types of circular polystyrene micropatterns with different diameters were formed and surrounded by PVA domains. Scale bars: 50 μm.
