Title: Innovations of Yang Dong in Biodegradable Cellulose Esters
Introduction
Yang Dong is an accomplished inventor based in Iowa City, IA (US). He has made significant contributions to the field of biodegradable materials, particularly in the development of cellulose esters. With a total of 2 patents, his work focuses on creating innovative solutions for drug delivery systems.
Latest Patents
Yang Dong's latest patents include "Biodegradable oxidized cellulose esters and their uses as microspheres" and "Biodegradable oxidized cellulose esters." The first patent describes a new cellulose excipient, OCCAE, which is suitable for use as a binder, filler, and/or disintegrant in solid dosage forms. It can also serve as a bodying agent or drug carrier in topical formulations. The cellulose excipient is formed by reacting an oxidized cellulose ester with an alcohol in the presence of a catalyst. This invention also details the formation of controlled release microspheres using OCCAE and/or oxidized cellulose esters, which can control drug release over several hours to days. The second patent relates to the preparation of oxidized cellulose esters that are suitable as drug carriers in biodegradable controlled and/or sustained release pharmaceutical, agricultural, and veterinary compositions. These esters are prepared by acylation of oxidized cellulose with at least 3% carboxyl groups, resulting in compounds that are soluble in aqueous alkaline solutions, water, and various organic solvents.
