摘要
随着纳米技术的飞速发展,三维复杂结构的金纳米星已成为一种新型纳米材料。金纳米星具有独特的物理化学性质,如可调制的局域表面等离激元光学特性、表面增强拉曼散射效应、光热特性、较大的比表面积等,这些性质使其在纳米材料和生物医学领域具有极高的潜在应用价值。本文首先介绍了近年来国内外金纳米星的合成方法,主要包括种子介导生长法和一步合成法(这两种制备方法均存在各自的优缺点),以及对金纳米星尺寸、枝杈的的调控研究;接着对金纳米星性质中的等离激元特性进行展开描述,并对其理论基础进行解释;本文对目前金纳米星在催化、SERS检测和生物医学领域最新研究进展进行了总结,并展望了金纳米星未来的研究内容和方向。
With the rapid development of nanotechnology,Au nanostars with complex three-dimensional structures have become a new type of nanoma-terials.Au nanostars have unique physical and chemical properties,such as tunable LSPR optical properties,SERS effect,photothermal properties,and large specific surface area.These properties make them highly potential applications in the fields of nanomaterials and biomedicine.This article first introduces the synthesis methods of Au nanostars at home and abroad in recent years,mainly including seed mediated growth method and one-step synthesis method,both of which have their own advantages and disadvantages,as well as the research on the regu-lation of the size and branching of Au nanostars.Then,the characteristics of plasmons in the properties of Au nanostars are described,and their theoretical basis is explained.Finally,it summarizes the latest research progress of Au nanostars in the fields of catalysis,SERS detection,and biomedicine,and looks forward to the future research content and direction of Au nanostars.
