Enantioselective sorting at the nanoscale is highly significant in fields such as medical research, material science, and drug development. However, previous studies mainly focus on static chiral particle separation, hindering practical applications. Here, we utilize the synergy between enantioselective potential wells and flow fields to sort nanoparticle enantiomers at a high velocity of 800 μm/s.

Article Synopsis
- Optical merons are unique structures found in surface plasmon polaritons and photonic crystals, created at the Γ-point in real space.
- These merons enable precise manipulation of different sizes of gold nanoparticles through strong radiation and optical gradient forces, allowing them to move or be trapped in specific patterns.
- This research demonstrates a new method for using topological effects in optics to achieve high-precision control at the nanometer scale without energy loss.
