Abstract

Systems and methods for delivering active ingredients, such as pharmaceutically active ingredients, to substrates are described herein. The active ingredients are delivered as fluids to a fluid-dispensing device for the creation of one or more drops for deposition onto substrates such as for the creation of microdoses. The invention further includes microdoses made by such processes.
