Enantiomeric forms of a drug molecule are known to vary in potency, toxicity and effect they might have on biological systems. Therefore, drug research and development demand to have enantiomers of all bioactive molecules separated and tested. We present a new, alternative method for the separation of racemic mixtures via single-atom-thick membranes, using functionalized nanoporous graphene as a template. Computational simulations based on density functional theory show that the attachment of a suitable chiral 'bouncer' molecule to the pore rim prevents the passage of the undesired enantiomer while letting its mirror image through. In contrast to common methods such as gas chromatography, high performance liquid chromatography and capillary electrophoresis, this allows an identification of a left- or right-handed drug molecule in a single molecular event.
