Dissymmetry is crucial for chiral geometries that utilize either intrinsic anisotropy forces around nanoparticles (NPs) or external organization associated with templates or applied fields and alignment. The chiral nanostructures in the geometries of dimers (different triggers), pyramids, and helices usually generate (−)/(+) enantiomers with tunable circular dichroism (CD) bands. The chiral superstructures of films produce much stronger, broader CD bands with tunable Cotton effect signs. Chiral fabrication has also been advanced by interdisciplinary technology. Surface enhanced Raman scattering (SERS), luminescence, and magneto-optics have been discussed in this study with respect to chiroptical properties. We have witnessed tremendous diversity in chiral assemblies with significant potential as biocompatible therapy reagents, biosensors, and catalysts as well as optical materials. In this study, we highlight the progress of chiral assemblies, especially geometrical and spectral tuning, and present a comprehensive discussion of their key parameters and mechanisms as well as their applications.

手性结构，结构多样性，规模转化和手性应用的调整

不对称性对于利用纳米粒子（NPs）周围的固有各向异性力或与模板或施加的场和排列相关的外部组织的手性几何至关重要。二聚体（不同的触发器），金字塔和螺旋的几何形状中的手性纳米结构通常会生成具有可调圆二色性（CD）谱带的（-）/（+）对映体。薄膜的手性上层结构会产生更强，更宽的CD带，并带有可调的棉花效应迹象。跨学科技术也促进了手性制造。在本研究中，就整脊特性讨论了表面增强拉曼散射（SERS），发光和磁光。我们目睹了手性组装的巨大多样性，它们具有巨大的潜力，如生物相容性治疗试剂，生物传感器，以及催化剂和光学材料。在这项研究中，我们重点介绍了手性组装的进展，特别是几何和光谱调谐，并全面讨论了它们的关键参数和机理及其应用。
