  We propose a method to separate enantiomers using parity violation in the
Casimir-Polder potential between chiral mirrors and chiral molecules. The
proposed setup involves a molecular beam composed of chiral molecules passing
through a planar cavity consisting of two chiral mirrors. Enantiomers of
opposite handedness are deflected differently due to a chiral dependence of the
Casimir-Polder potential resulting in the separation of the enantiomers. Our
setup provides an alternative experimental tool for enantiomer separation, as
well as shedding light on the fundamental properties of the Casimir-Polder
potential.
