Nanotubes Could Form Basis of New Drug-Purification

Gina Miller writes "Scientific American.com has an article Nanotech Tubes Could Form Basis of New Drug-Purification Techniques that reports a way to purify drug molecules away from their inactive mirror image molecules. The scientist's created antibodies that recognize only the proper mirror image and place the antibodies in silicon nanotubes inside a membrane. As a result the drug molecules flow across the membrane five times faster than the undesired mirror image."
