由于其高度的完整性、容易的表面化学、优异的稳定性以及来自核和壳材料的双重性质，磁性-等离子体核-壳纳米颗粒在许多科学、工程和生物医学学科中引起了极大的兴趣。它们在催化、能量转换、生物分离、医学成像、疾病检测和治疗等广泛领域有着广阔的应用前景。技术应用已经驱动了对具有良好控制的磁性和光学性质的高质量纳米颗粒的需求。在过去的几十年中，在合成和表征磁性等离子体核壳纳米颗粒，主要是氧化铁-金核壳纳米颗粒方面取得了巨大的进展。本文介绍了球形和各向异性磁等离子体核壳纳米粒子的合成方法，重点介绍了氧化铁-金核壳纳米粒子。生长机制进行了讨论，以提供控制形状控制合成的关键因素的理解。磁性和光学性质的计算和实验研究进行了总结。本文综述了不同形状的氧化铁-金核壳纳米粒子的合成方法、磁性和光学性质。
Due to their high integrity, facile surface chemistry, excellent stability, and dual properties from the core and shell materials, magnetic-plasmonic core-shell nanoparticles are of great interest across a number of science, engineering and biomedical disciplines. They are promising for applications in a broad range of areas including catalysis, energy conversion, biological separation, medical imaging, disease detection and treatment. The technological applications have driven the need for high quality nanoparticles with well controlled magnetic and optical properties. Tremendous progress has been made during past few decades in synthesizing and characterizing magnetic-plasmonic core-shell nanoparticles, mainly iron oxide-gold core-shell nanoparticles. This review introduces various approaches for the synthesis of spherical and anisotropic magnetic-plasmonic core-shell nanoparticles focusing on iron oxide-gold core-shell nanoparticles. Growth mechanisms are discussed to provide understanding of the key factors controlling shape-controlled synthesis. Magnetic and optical properties are summarized from both computational and experimental studies. This review introduces and discusses synthetic approaches, magnetic and optical properties of iron oxide-gold core-shell nanoparticles in different shapes.
