具有高度扭曲的电磁场的手性近场的手性构建了一座桥，以匹配手性分子和具有较大尺寸差异的光波长。它显着增强了手性分子的圆二色性，并且在手性传感，检测，诱捕和其他与手性相关的应用方面具有很大的前景。表面等离子体具有出色的光捕获和电磁场浓缩能力。等离子手性纳米结构有助于轻巧的操纵，从而在田野附近产生超级手续。同时，由于其独特的电磁谐振特性，纳米光子结构引起了重大兴趣，以获得强烈的手性场。在光和手性材料的相互作用期间，近场的手性不仅桥接光和手性分子，而且还负责光学活动。本文回顾了使用等离子和光子纳米结构的手性近场增强的最新研究。我们回顾了手性电磁场的原理以及血浆和光子纳米结构的发展，以近场增强。检查了增强手性分子检测，自旋角相互作用以及手性光学力的产生的近田的性质和应用。最后，我们讨论当前的挑战，并简要介绍该领域。
A chiral near field with a highly contorted electromagnetic field builds a bridge to match the chiral molecules and light wavelengths with large size differences. It significantly enhances the circular dichroism of chiral molecules and has great prospects in chirality sensing, detection, trapping, and other chirality-related applications. Surface plasmons feature outstanding light-trapping and electromagnetic-field-concentrating abilities. Plasmonic chiral nanostructures facilitate light manipulation to generate superchiral near fields. Meanwhile, the nanophotonic structures have attracted significant interest to obtain strong chiral fields due to their unique electromagnetic resonant properties. During the interaction of light and chiral materials, the chiral near field not only bridges the light and chiral molecules but is also responsible for the optical activities. This paper reviews state-of-the-art studies on chiral near field enhancement using plasmonic and photonic nanostructures. We review the principle of chiral electromagnetic fields and the development of plasmonic and photonic nanostructures for near field enhancement. The properties and applications of enhanced chiral near fields for chiral molecule detection, spin-orbit angular interaction, and the generation of the chiral optical force are examined. Finally, we discuss current challenges and provide a brief outlook of this field.
