1. A composition for in vivo delivery of a biologic,wherein said biologic is selected from:
- a solid, optionally dispersed in a biocompatible dispersing agent, substantially completely contained within a polymeric shell,a liquid, optionally dispersed in a biocompatible dispersing agent, substantially completely contained within a polymeric shell,a gas, optionally dispersed in a biocompatible dispersing agent, substantially completely contained within a polymeric shell,a gas associated with a polymeric shell, or combinations of any two or more thereof,wherein the largest cross-sectional dimension of said shell is no greater than about 10 microns,wherein said polymeric shell comprises a biocompatible material which is substantially crosslinked by way of disulfide bonds, andwherein said polymeric shell is optionally modified by a suitable agent, wherein said agent is optionally associated with said polymeric shell through an optional covalent linkage.

Abstract
In accordance with the present invention, there are provided compositions useful for the in vivo delivery of a biologic, wherein the biologic is associated with a polymeric shell formulated from a biocompatible material. The biologic can be associated with the polymeric shell itself, and/or the biologic, optionally suspended/dispersed in a biocompatible dispersing agent, can be encased by the polymeric shell. In another aspect, the biologic associated with polymeric shell is administered to a subject, optionally dispersed in a suitable biocompatible liquid.
