Chirality-assisted lateral momentum transfer for bidirectional enantioselective separation

Light carrying photon momentum can push and pull microparticles through momentum exchange. This momentum exchange process generates optical forces, which either attracts (conventional optical tweezers), pushes (radiation force) or pulls (pulling force) microparticles. A new emerging research interest, optical lateral force which represents the optical force perpendicular to the propagating direction of a non-gradient beam, has attracted much attention. The lateral force can be generated using ac...
