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.
多元素纳米颗粒（PE NPs）在单个 NP 中含有四种或更多种元素，与它们的单元素对应物相比具有有趣的固有特性。不同元素的融合会产生协同效应，包括新的物理和化学现象。然而，传统方法并未提供有效的策略来均匀地创建具有高重现性的 PE NPs。最近，随着纳米科学的进步，已经开发出了几种使用热力学和动力学方法的新方法，并且通常是它们之间的相互作用。在本观点中，我们重点介绍了在设计 PE NPs 及其基础形成机制方面的最新关键进展。我们讨论了 PE NPs 的潜在应用以及该领域的展望和未来方向。
