Abstract
A method of making microcapsules including activating a fluid ejector at a frequency greater than 10 kilohertz where each activation of the fluid ejector generates essentially a drop, and the fluid ejector is fluidically coupled to a first fluid including a core component. The method further includes ejecting the drop of the first fluid into a second fluid, the drop having a volume. In addition, the method includes generating a microcapsule, that includes the core component, in the second fluid for each drop of the first fluid ejected.
