  We put forward a novel, twofold scheme that enables at the same time
all-optical enantioselection and sorting of single multipolar chiral
microspheres based on optical pulling forces exerted by two non-collinear,
nonstructured, circularly-polarized light sources. Our chiral resolution method
can be externally controlled by varying the angle between their incident
wavevectors, allowing for a fine-tuning of the range of chiral indices for
enantioselection. Enantioselectivity is achieved by choosing angles such that
only particles with the same handedness of the light sources are pulled. This
proposal allows one to achieve all-optical sorting of chiral microspheres with
arbitrarily small chiral parameters, thus outperforming current optical
methods.
