Methods for in vivo delivery of nutriceuticals and compositions useful therefor
First Claim
1. A method for the preparation of articles for in vivo delivery of nutriceuticals, said method comprising subjecting aqueous medium containing biocompatible material capable of being crosslinked by disulfide bonds and a nutriceutical to high intensity ultrasound conditions for a time sufficient to promote crosslinking of said biocompatible material by disulfide bonds;
- wherein said nutriceutical is substantially contained within a polymeric shell, andwherein the largest cross-sectional dimension of said shell is no greater than about 10 microns.

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.
