摘要： Among other things, for use in directional motion of chiral objects in a mixture, a field is applied across the chamber and is rotating relative to the chamber to cause rotation of the chiral objects. The rotation of the objects causes them to move directionally based on their chirality. The method applies to sugars, proteins, and peptides, among other things, and can be used in a wide variety of applications.
