Abstract
The present invention generally relates to novel overcoating/encapsulation processes which are carried out in solution without the use of droplet generation devices. The processes may be used in the overcoating or encapsulation of a variety of materials, such as biological material, e.g., cells, proteins, etc., as well as pharmaceuticals. Compositions prepared using the methods of the present invention may find use in pharmaceutical formulation as well as coating biological material for a number of applications, including cell culturing and transplant therapy.
