    • 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.
    • 一种包括具有含氟聚合物的模具的系统,其中所述模具限定具有预定形状和横截面尺寸小于约100微米的多个空腔; 滚筒 与辊协作以形成被配置为接收模具的夹持点的表面,其中夹持点进一步构造成接收基本上液体的组合物并加速基本上液体的组合物进入空腔。 一种形成颗粒的方法,包括将基本上液体的组合物施加到模具,其中所述模具包括含氟聚合物并且限定多个空腔,每个空腔具有小于约100微米的最宽的横截面尺寸; 将模具夹在辊和表面之间,使得基本上液体的组合物进入模具的空腔; 并且在模具的空腔中硬化基本上液体的组合物以在每个空腔内形成颗粒,其中颗粒具有基本上模拟模具空腔的尺寸和形状的尺寸和形状。
