摘要

纵向米氏共振在硅纳米片上，由一个方位-径向极化光束激发，产生强大的光学手性梯度和最小的非手性背景。磁四极子模式可以实现选择性对映体捕获，即使对弱手性纳米颗粒也能实现超过100的预测选择性和稳健的性能，为光学对映体分离提供了一种无创途径。

Enhanced Enantioselective Optical Trapping Enabled by Longitudinal Mie Resonances in Silicon Nanodisks

Longitudinal Mie resonances in silicon nanodisks, excited by an azimuthally–radially polarized beam, generate strong optical chirality gradients with minimal achiral background. Magnetic quadrupole modes enable selective enantiomer trapping, achieving predicted selectivities over 100 for and robust performance even for weakly chiral nanoparticles, offering a noninvasive route to optical enantioseparation.
