摘要： The present invention is directed to electrostatic chucks, methods for their use, the electrostatic deposition of objects, such as particles in a dry powder, onto recipient substrates, and the recipient substrates themselves that have been subjected to electrostatic deposition. In one aspect, the present invention provides an electrostatic chuck for electrostatically attracting an object or objects wherein the object is used in chemical or pharmaceutical assaying or manufacturing. The objects can be pharmaceutical substrates, for example, such as a pharmaceutical tablet. Additional embodiments of the invention provide chucks and their use to electrostatically attract particles, such as a pharmaceutically active ingredient, to a substrate, such as a tablet. In one aspect, the electrostatic chuck comprises a floating electrode, and is used to selectively attract particles to a substrate above the floating electrode, thereby providing for charge imaging for the deposition of particles in a selected image. Additionally, the invention provides comprising a sensing electrode, optionally for use with an electrostatic chuck, for sensing the number of particles attracted to the objects on the chuck or other substrate, thereby providing for deposition of an accurate amount of particles. Furthermore, the present invention provides objects having selected areas in which particles are applied to the object via electrostatic means.
