Separation of chiral particles in micro- and nanofluidic systems — •Ralf Eichhorn — Nordic Institute for Theoretical Physics (Nordita), Stockholm, Sweden

Standard techniques for separating a mixture of chiral molecules (enantiomers) rely on chiral auxiliary substances. We discuss the alternative possibility to sort chiral molecules by their distinct physical behavior in external force fields without making use of additional chiral agents. Using numerical simulations and theoretical arguments, this separation concept is demonstrated for simple model systems, and the basic physical mechanisms are illustrated and analyzed. Furthermore, experimental realizations in microfluidic systems are presented.
