与单元素纳米粒子相比，在单个纳米粒子中含有四个或更多元素的多元素纳米粒子具有耐人寻味的固有性质。多种元素的融合产生了包括新的物理和化学现象在内的协同效应。然而，传统的方法并没有提供有效的策略来均匀地制备具有高重复性的PE纳米粒子。最近，随着纳米科学的进步，已经开发了几种新的方法，使用热力学和动力学方法，通常是它们之间的相互作用。在这一视角下，我们重点介绍了PE NPs设计及其基本形成机制方面的最新进展。讨论了PE纳米粒子的潜在应用以及该领域的前景和未来的发展方向。
Polyelemental nanoparticles (PE NPs) containing four or more elements in a single NP have intriguing intrinsic properties compared to their single-element counterparts. The fusion of diverse elements induces synergistic effects including new physical and chemical phenomena. However, conventional methods have not offered effective strategies for the uniform creation of PE NPs with high reproducibility. Recently, with advances in nanoscience, several new methods have been developed using both thermodynamic and kinetic approaches and, often, the interplay between them. In this Perspective, we highlight recent key advances in the design of PE NPs and their underlying formation mechanisms. We discuss the potential applications of PE NPs and the outlook and future directions for this field.
