摘　　要：手性描述了一个物体不能与其镜像重叠的几何性质,自19世纪以来一直是化学和生物学中的一个关键概念。随着纳米技术的发展,手性等离子体纳米材料凭借其特殊的手性光学性质和良好的生物相容性已经成为科学家们的研究重点和手性功能材料开发的热点。然而,较弱的手性响应信号限制了其应用和发展。将手性等离子体纳米材料和核壳结构结合得到的手性等离子体核壳纳米结构是一种放大手性响应信号的有效策略。核壳纳米结构整合了内外两种材料的性质,互相补充各自的不足,能够进一步改善材料的物理化学性质,提升材料在各个领域的性能。本文依据手性分子的空间分布对手性等离子体核壳纳米结构的设计策略进行了总结,并综述了其在超灵敏传感和手性催化领域的应用,分析了目前尚存在的问题和可能的解决方式,对其未来的发展作了进一步展望。Chirality describes the geometrical feature of an object that cannot overlap with its mirror image and has been a crucial concept in chemistry and biology since the 19th century.With the development of nanotechnology,chiral plasmonic nanomaterials are becoming the research focuses for scientists to develop chiral functional materials due to the special chiral optical properties and good biocompatibility.However,the relatively weak chiral signals limit their applications.Chiral plasmonic core-shell nanostructures combine the chiral plasmonic properties and core-shell structures,which is an effective strategy to amplify chiral signals.In addition,the core-shell nanostructure integrates the properties of both internal and external materials to complement each other,which can further improve the physicochemical properties and enhance the performance in various fields.This paper summarizes the design strategies of chiral plasmonic core-shell nanostructures based on the spatial distribution of chiral molecules,and reviews their applications in the fields of ultrasensitive sensing and chiral catalysis.We analyze the existing problems and their possible solutions,and make an outlook on their future development.
