Abstract
A system including a mold having a fluoropolymer wherein the mold defines a plurality of cavities having a predetermined shape and a cross-sectional dimension less than about 100 micrometers; a roller; a surface in cooperation with the roller to form a nip point configured to receive the mold, wherein the nip point is further configured to receive a substantially liquid composition and accelerate entry of the substantially liquid composition into the cavity. A method of forming particles including applying a substantially liquid composition to a mold, wherein the mold comprises a fluoropolymer and defines a plurality of cavities each having a broadest cross-sectional dimension of less than about 100 micrometers; nipping the mold between a roller and a surface such that the substantially liquid composition enters the cavities of the mold; and hardening the substantially liquid composition in the cavities of the mold to form a particle within each cavity, wherein the particle has a size and shape that substantially mimics the size and shape of the cavity of the mold.
