Two‐faced character in a film : Soft “Janus” two‐dimensional colloidal crystal films were made using polystyrene (PS) particles, on an air–water interface as a mold for a flexible polypyrrole layer. By removing the PS particles, an array of femtoliter‐sized cups was produced. These two‐dimensional colloidal crystal films can also be transferred onto substrates with curvature.
