A nonlithographic breath‐figure method is used to obtain ordered arrays of pores in polymer films. The pore size depends on the viscosity of the polymer solution, and is readily controlled by varying the composition of the polymer. Microbeads are patterned on the films using the pores as a template (see figure); the size of the microbeads should match that of the pores to obtain a stable array of microbeads.
