FLUID-JET PENS CONFIGURED FOR MAKING MODULATED RELEASE BIOACTIVE AGENTS

摘要

The present invention is drawn to methods of preparing a bioactive agent-containing emulsion for delivery to a biological system. This method c an comprise the step of jetting a bioactive agent and a first fluid medium from a fluid-jet pen into a second fluid medium to form a bioactive agent-containin g emulsion, wherein the second fluid comprises a continuous phase of the emulsion. Alternatively, a method of preparing a bioactive agent-containing liposome can comprise jetting a lipid-containing composition and a bioactive agent from a fluid-jet pen into a medium to form a bioactive agent-containin g liposome carried by the medium.
