Chiral Rayleigh particles discrimination in dynamic dual optical traps

- A chiral optical conveyor belt for enantiomeric separation of nanopar-ticles is numerically demonstrated.
- Chiral resolution has been theoretically analyzed for chiral spheres immersed in water.
- Electromagnetic fields have been designed for obtaining Chiral selective optical tweezers to separate enantiomers in different spatial regions.

A chiral optical conveyor belt for enantiomeric separation of nanoparticles is numerically demonstrated by using different types of counter propagating elliptical Laguerre Gaussian beams with different beam waist and topological charge. The analysis of chiral resolution has been made for particles immersed in water demonstrating that in the analyzed conditions one type of enantiomer is trapped in a deep potential and the others are transported by the chiral conveyor toward another trap located in a different geometrical region.
