Abstract

This article reviews the latest developments in the field of chiral nanocrystals (NCs), focusing primarily on plasmonic NCs. Such nanomaterials under illumination concentrate electromagnetic energy in their vicinity, enabling efficient biosensing, asymmetric photocatalysis, and light manipulation. Starting our discussion with Lord Kelvin’s definition of chirality, we describe how enantiomer pairs appear when the molecule becomes progressively more complex. Making a comparison with Pasteur’s chirality of molecules, we discuss nanoscale enantiomers lacking exact mirror symmetry, so-called nonexact enantiomers, and why they should appear fundamentally. Whereas chirality is an intrinsically three-dimensional (3D) concept describing perfect mirror-imaged pairs, a novel property of pseudo-chirality is handy for understanding two-dimensional (2D) systems, including the case of plasmonic growth with circularly polarized light. The topics considered in the review include bio-templated NCs, chiral bio-assemblies, transfer of chirality from biomolecules to NCs, chirality and pseudo-chirality in 3D and 2D systems, growth of NCs under circularly polarized excitation, and more.

从手性生物分子到手性纳米晶体：最新发展和新兴概念综述

本文综述了手性纳米晶体领域的最新进展，重点介绍了等离子体纳米晶体的研究进展。这种纳米材料在光照下将电磁能量集中在其附近，从而实现高效的生物传感、不对称光催化和光操纵。从开尔文勋爵对手性的定义开始讨论，我们描述了当分子变得越来越复杂时对映体对是如何出现的。通过与巴斯德分子手性的比较，我们讨论了缺乏精确镜像对称的纳米级对映体，即所谓的非精确对映体，以及为什么它们应该从根本上出现。虽然手性本质上是一个描述完美镜像对的三维（3D）概念，但伪手性的一个新特性有助于理解二维（2D）系统，包括圆偏振光等离子体生长的情况。本文讨论的主题包括生物模板化NCs、手性生物组件、手性从生物分子到NCs的转移、3D和2D系统中的手性和伪手性、圆极化激发下NCs的生长等。
