Title: The Innovations of Stephen S. Schwartz

Introduction

Stephen S. Schwartz is an accomplished inventor based in State College, PA (US). He holds two patents that showcase his expertise in the field of biological materials processing. His work has significantly contributed to advancements in the storage and rehydration of biological substances.

Latest Patents

One of Schwartz's latest patents is for an "Integrated container for lyophilization, rehydration and processing of biological materials." This innovative apparatus is designed to lyophilize, store, transport, rehydrate, and process aqueous biological materials while maintaining sterility. The container allows for shrinkage after lyophilization and optimally permits filtration or dialysis of the contents in situ, eliminating the need for additional containers. The microporous container is constructed from a membrane that is water vapor permeable yet water impermeable, ensuring the integrity of its contents.

Another significant patent is for "pH dependent membrane diffusion." This invention involves a pore plugging material that utilizes cyclic olefins with phosphazene-functional moieties. These materials provide predictable erosion properties when used to plug pores in separation barriers and other porous membranes. The unique characteristics of these polymers depend on various factors, including molecular weight and the identity of side groups attached to the phosphazene moiety. As a class, phosphazene-functional cyclic olefins offer predictable erodibility and benign hydrolysis products, making them suitable for use in separation barriers and membranes.
