摘要
近红外光热转换纳米晶材料因其在近红外区(普遍位于780~1 400 nm)的高效光热转换性能,已广泛应用于光热杀死癌细胞、肿瘤治疗、海水淡化等领域。因其多样的液相制备方法和形貌控制、纳米结构复合、逐渐提高的光热转换效率以及表面易于药物修饰等优点,该材料在光热成像诊断、光热治疗等领域引起了学术界的广泛关注。本文综述了近红外光热转换纳米晶的研究进展,主要包括贵金属纳米晶、铜硫族半导体纳米晶、碳相关纳米晶以及这些纳米晶材料构成的复合结构,同时介绍了具有较高光热转换效率的表面等离子体共振(SPR)材料的研究进展,尤其是双模态SPR性质的耦合在光热转换领域的应用前景。基于其性能协同耦合的特性,双模态表面等离子体共振耦合的复合纳米晶将是近几年光热转换纳米晶发展的重要方向。
Abstract
Near-infrared photothermal(PT) conversion nanocrystals(NCs), due to their excellent PT conversion performance in near-infrared region(generally in range of 780-1 400 nm), has a wide application potential in the field of cancer cell killing, tumor therapy as well as desalination. These NCs attracted great attention on PT imaging and PT therapy, because of their diverse liquid phase synthesize methods, morphology-controll, nanostructure composite, increasing PT conversion efficiency and easy functionalization . This review aimed to summarize the research progress of near-infrared PT conversion NCs, including noble metal NCs, copper chalcogenide semiconductor NCs, carbon-related NCs, hybrid structure composed of nanocrystalline materials. In addition, the research progress of surface plasmon resonance(SPR) materials with high photothermal conversion efficiency is introduced, especially the application prospect of dual-mode SPR coupling in the field of photothermal conversion. Through the research on the literatures at home and abroad, it is known that the hybrid nanocrystals with dual mode surface plasmon resonance coupling will be an important direction for the development of photothermal conversion nanocrystals in recent years due to the characteristics of performance coordination and coupling.
