We propose a gain-assisted enantioselective scheme in dye-doped chiral core-shell particles using a single plane wave. We demonstrate that optical pulling and pushing forces on the gainfunctionalized chiral particles can be achieved and tuned using externally controllable parameters using dye molecules concentration and pumping rate. The results demonstrate that controlling the pump rate allows one to efficiently exert pulling forces on a given chiral enantiomer, while pushing the enantiomer of opposite handedness, demonstrating an all-optical chiral resolution of racemic mixtures. Since this scheme depends on the gain of single chiral particles, which also compensate for optical losses, this method may be applied not only to lossless chiral particles but also to lossy plasmonic chiral particles.
