Porous Silica Shell-mediated Assembly of Macromolecular Capsules

The present invention relates to a process of preparing macromolecular capsules. In particular, the invention relates to the use of a template with a permeable shell and an impermeable core for preparing macromolecular capsules. The process of the present invention relates to infiltrating macromolecules such as polymers into a permeable shell and then crosslinking the macromolecules to form a macromolecular network within the pores of the permeable shell. In some cases, the permeable shell and impermeable core can both be removed to yield hollow capsules. The invention involves the use of macromolecules which may be conjugated to one or more functional molecules. In some cases the macromolecules used in the invention are conjugated to biologically active molecules to form particles useful for applications including, but not limited to, drug delivery and controlled release.
