Abstract
A method of preparing particles comprises forming by optical lithography a topographic template layer disposed on a surface of a substrate, which is suitable for spin casting. The template layer comprises a non-crosslinked template polymer having a pattern of independent wells therein for molding independent particles. Spin casting a particle-forming composition onto the template layer forms a composite layer comprising the template polymer and the particles disposed in the wells. The composite layer is removed from the substrate using a stripping agent that dissolves the template polymer without dissolving the particles. The particles are then isolated.
