Abstract
A method for producing particles includes providing a first patterned surface having a first surface relief pattern adapted to impart structure to a plurality of particles while they are under production; providing a second patterned surface having a second surface relief pattern adapted to impart structure to a plurality of particles while they are under production; depositing a particle material in contact with at least one of the first patterned surface and the second patterned surface; aligning the first surface relief pattern on the first patterned surface with respect to the second surface relief pattern on the second patterned surface; contacting at least a portion of the first patterned surface with at least a portion of the second patterned surface; solidifying at least a portion of the particle material to form a plurality of particles; and separating at least a portion of the plurality of particles from at least one of the first patterned surface and the second patterned surface. The at least a portion of a structure of each of the plurality of particles is imparted by a combination of the first surface relief pattern and the second surface relief pattern.
