Methods for the preparation of nucleic acids for in vivo delivery
First Claim
1. A method for the preparation of articles for in vivo delivery of nucleic acid constructs, said method comprising subjecting aqueous medium containing biocompatible material capable of being crosslinked by disulfide bonds and nucleic acid construct to high intensity ultrasound conditions for a time sufficient to promote crosslinking of said biocompatible material by disulfide bonds;
- wherein said nucleic acid construct is substantially completely 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.
