Biologically active membranes separate drugs

Mr_Farlops writes "Researchers in Finland and the United States have developed a method that may soon cheaply refine highly pure drugs. Using a membrane composed of tailored antibodies bound to the interiors of silca nanotubes, they discovered a way to separate wanted drug molecules from unwanted enantiomers (molecules with the same chemical composition but mirror-imaged structure.) and side products. The process might become commonly used in 5 to 10 years."
