Title: David S. Scher: Innovator in Targeted Delivery Systems
Introduction
David S. Scher is a notable inventor based in Hudson, MA (US). He has made significant contributions to the field of targeted delivery systems, particularly in the development of sustained release compositions for biologically active agents. With a total of 3 patents to his name, Scher continues to push the boundaries of innovation in therapeutic delivery methods.
Latest Patents
One of Scher's latest patents focuses on methods and compositions for the targeted delivery of biologically active agents. This invention relates to a sustained release composition designed for the targeted delivery of biologically active agents to specific tissues and cells. The composition comprises microparticles that contain a biocompatible polymer, a water-soluble polymer, and a biologically active agent. In one embodiment, the biologically active agent is an antigen or an immunomodulator, while in another embodiment, it is a labile agent. The microparticles have a number median diameter of greater than 20 microns upon administration. The water-soluble polymer is present in the sustained release composition in at least about 20% of the dry weight of the microparticle. This composition allows for the dissolution of the water-soluble polymer upon hydration at a much greater rate than the degradation of the biocompatible polymer. This variance in solubility generates pseudo-microparticles that can be engulfed by antigen-presenting cells of the immune system or absorbed by the Peyer's patches in the gut.
