Title: Paul C Stearns: Innovator in Microparticle Technology
Introduction
Paul C Stearns is a notable inventor based in Redwood City, CA (US). He has made significant contributions to the field of drug delivery systems, particularly through his innovative work on microparticles. With a total of 3 patents, Stearns has focused on developing methods for controlled release of biologically active drugs.
Latest Patents
Stearns' latest patents include a formulation for ICAM-1 that utilizes controlled-size microparticles. This method and system are designed for producing microparticles loaded with biologically active drugs, including proteins such as ICAM-1, for controlled release in the nasal passageway. The process involves introducing a drug/polymer feed solution and an emulsifier into a first mixing chamber to create an emulsion. A cross-linking agent is then mixed with the emulsion under controlled conditions to create the microparticles. The system features a first mixing chamber with ports for introducing the drug/polymer solution and emulsifier, as well as a second mixing chamber that solidifies the microparticles. The final product is filtered and deaggregated to form individual microparticles suitable for nasal delivery.
