In this work, we fabricated a designed 2D polymer pattern by embossing and replica molding using colloidal stamps that were prepared from self-assembled particle arrays in a soft, patterned PDMS mold. For a successful pattern transfer, polymer infiltration at the interstices between the silica spheres of the colloidal stamp was controlled by depositing a thin gold layer.
