ABSTRACT:
Electrostatic phototechnology is used to package microgram quantities of fine powders such as drugs. An electrostatic "image" having a given size and charge density is exposed to ionized drug powder to attract a known amount of drug to the image. The resultant drug "image", is then transferred to a package.
