Engineering of radiation of optically active molecules with chiral nano-meta-particles

The radiation of an optically active (chiral) molecule placed near a chiral nanosphere is investigated. The optimal conditions for engineering of radiation of optically active (chiral) molecules with the help of chiral nanoparticles are derived. It is shown that for this purpose, the substance of the chiral particle must have both epsilon and mu negative (double negative material (DNG)) or negative mu and positive epsilon (mu negative material (MNG)). Our results pave the way to an effective engineering of radiation of left and right molecules and to creating pure optical devices for separation of drugs enantiomers. Copyright (C) EPLA, 2012
