Artificial skin is a collagen scaffold that induces regeneration of skin in mammals such as humans. The term was used in the late 1970s and early 1980s to describe a new treatment for massive burns.

What Is UF Membrane? Performance of UF Membrane and Advantages of UF Technology Ultrafiltration is basically a pressure-driven membrane process that separates by molecular weight. The UF membrane pore size is generally between 1 and 100 nm, and it can cut off substances with a molecular weight of 300 to 500,000 Daltons, including polysaccharides, biomolecules, polymers and colloidal substances. The nominal cut molecular weight of most UF membranes is generally defined as the smallest molecular weight at which the china membrane has a rejection of greater than 90%.
