US Kidney Research Corporation (USKRC), in collaboration with the University of Arkansas, has developed an innovative ultrafiltration membrane with a wide range of potential applications in both medical and non-medical devices. Unlike conventional membranes currently used in the industry, this new ultrafiltration membrane offers superior filtration efficiency, durability, and performance, making it a breakthrough in the field. This advanced membrane is particularly suited for use in dialyzers, which are essential components of hemodialysis machines, responsible for filtering blood and removing waste products and excess fluids from a patient's body during the dialysis process.

​
The new membrane is capable of increased ultrafiltration flux, and better dialysis performance. Among its notable features are excellent biocompatibility, ability to clear potential uremic toxins, and stability. The work, published in a recent Nature article in Scientific Reports (13(1), 11703), describes the development of the new membrane created through a tempo-cellulosic oxidation process and cast using ionic liquids. Because of the unique nature of the membrane after casting, it has an extremely high flux and high rejection of BSA in ultrafiltration mode. The alignment of fibers in the final structure allow for superior performance compared to traditional dialysis membranes.

​

Beyond its use in dialysis, the membrane shows great promise for various other applications, including laboratory use, vaccine water purification, veterinary devices, and wastewater filtration. Its versatility, combined with its enhanced capabilities, positions it as an exceptional alternative to existing membranes, offering improved performance and reliability across a broad spectrum of industries.
