Abstract
A method for producing particles includes providing a relief template having a surface relief pattern adapted to impart structure to a plurality of particles while they are under production; depositing a radiation-sensitive material on the relief template; exposing portions of the radiation-sensitive material on the relief template using a beam of spatially patterned radiation; removing portions of the radiation-sensitive material after the exposing to reveal at least portions of surfaces of the plurality of particles; and separating at least a portion of the plurality of particles from the relief template. At least a portion of a structure of each of the plurality of particles is defined by a combination of the surface relief pattern and the spatially patterned radiation.
