Design and application study of cell microcapsulation instrument.

This paper describes a device designed for controlling the size of cell-enveloping microcapsules. Microcapsule size varied inversely with air flow rate; an empirical formula was obtained relating packing density to microcapsule diameter. Microcapsule loading and cell distribution in the microcapsule are discussed. Finally, choice of microcapsule size is assessed, showing that smaller microcapsules result in better clone development.
