Introduction

Mark R Etzel is a notable inventor based in Madison, Wisconsin, with a remarkable portfolio of 18 patents. His work primarily focuses on advancements in filtration technologies and methods for isolating milk proteins.

Latest Patents

Among his latest innovations is the "Diffusion transfer functionalized membrane," which describes a method of creating a filter designed to effectively filter proteins from solutions. This method involves contacting a porous, polymeric substrate with a transfer liquid that includes solvents and charged polymeric solutes. The process utilizes a Hansen Solubility Parameter distance of approximately 10 to 35, allowing the polymeric substrate to accept the charged solute through diffusion transfer. The removal of the transfer liquid subsequently traps the solute on the substrate's surface, resulting in a functionalized filter medium. Additionally, he has developed methods and compositions involving whey protein isolates, which utilize charged ultrafiltration processes that leverage pH variations to separate different protein species.
