这篇专题文章概述了银纳米片的合成和性能的研究现状。从一个简单的描述银纳米粒子的光学性质的起源和影响它们的因素，我们介绍了用于建模离散偶极子近似（DDA）和边界元法（BEM）的数值方法，并提出了理论预测和实验结果之间的比较研究。然后，主要的物理和湿化学合成协议，已被用来获得银纳米三角形/纳米板在高产量的描述，与讨论的形成机制提出了不同的作者。随后，描述了颗粒的结构表征，随后是专门用于银纳米片的反应性和稳定性的部分。最后，我们的生物和化学传感器和表面增强拉曼光谱（Sers）领域的潜在应用的描述。
This Feature Article provides an overview of current research on the synthesis and properties of silver nanoplates. Starting from a brief description of the origin of the optical properties of Ag nanoparticles and the factors affecting them, we introduce the numerical methods used for modelling-discrete dipole approximation (DDA) and boundary element method (BEM)-and present a comparative study between theoretical predictions and experimental results. Then, the principal physical and wet-chemical synthetic protocols that have been used to obtain Ag nanotriangles/nanoplates in high yield are described, with a discussion of the formation mechanisms proposed by the different authors. Subsequently, the structural characterization of the particles is described, followed by a section devoted to the reactivity and stability of silver nanoplates. We conclude with a description of potential applications in the field of biological and chemical sensors and surface enhanced Raman spectroscopy (SERS).
