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 ε and μ negative (double negative material (DNG)) or negative μ and positive ε (μ 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.
