Abstract Chirality is one of the most fascinating occurrences in the natural world and plays a crucial role in chemistry, biochemistry, pharmacology, and medicine. Chirality has also been envisaged to play an important role in nanotechnology and particularly in nanophotonics, therefore, chiral and chiroptical active nanoparticles (NPs) have attracted a lot of interest over recent years. Optical activity can be induced in NPs in several different ways, including via the direct interaction of achiral NPs with a chiral molecule. This results in circular dichroism (CD) in the region of the intrinsic absorption of the NPs. This interaction in turn affects the optical properties of the chiral molecule. Recently, studies of induced chirality in quantum dots (QDs) has deserved special attention and this phenomenon has been explored in detail in a number of important papers. In this article, we review these important recent advances in the preparation and formation of chiral molecule–QD systems and analyze the mechanisms of induced chirality, the factors influencing CD spectra shape and the intensity of the CD, as well as the effect of QDs on chiral molecules. We also consider potential applications of these types of chiroptical QDs including sensing, bioimaging, enantioselective synthesis, circularly polarized light emitters, and spintronic devices. Finally, we highlight the problems and possibilities that can arise in research areas concerning the interaction of QDs with chiral molecules and that a mutual influence approach must be taken into account particularly in areas, such as photonics, cell imaging, pharmacology, nanomedicine and nanotoxicology.

半导体纳米晶体中配体诱导的手性和光学活性：理论和应用

摘要 手性是自然界中最迷人的现象之一，在化学、生物化学、药理学和医学中起着至关重要的作用。手性也被设想在纳米技术中发挥重要作用，特别是在纳米光子学中，因此，近年来手性和手性活性纳米粒子 (NPs) 引起了很多兴趣。可以通过几种不同的方式在 NPs 中诱导光学活性，包括通过非手性 NPs 与手性分子的直接相互作用。这导致在 NPs 的本征吸收区域中产生圆二色性 (CD)。这种相互作用反过来影响手性分子的光学性质。最近，量子点 (QD) 中诱导手性的研究值得特别关注，并且在许多重要论文中详细探讨了这种现象。在本文中，我们回顾了手性分子-QD 系统制备和形成方面的这些最新进展，并分析了诱导手性的机制、影响 CD 光谱形状和 CD 强度的因素，以及 QD 对手性分子。我们还考虑了这些类型的手性量子点的潜在应用，包括传感、生物成像、对映选择性合成、圆偏振光发射器和自旋电子器件。最后，
