Research Progress of Gold Nanorods Based Intelligent Composite Nanogels

金纳米棒(AuNRs)基智能复合纳米水凝胶是一类结合了AuNRs和智能纳米水凝胶两者独特性能的智能纳米材料,其最大特点是可通过外界刺激来调节AuNRs的多种性能,或通过测定其性能变化来感知外界刺激。本文首先介绍了目前文献报道的核壳结构型、无规充填型、草莓型三种形态结构的AuNRs基智能复合纳米水凝胶的特点及其合成方法。然后,总结了金纳米棒基智能复合纳米水凝胶的性能与应用研究进展。最后,对其未来的研究方向和发展前景作出了展望。

Gold nanorods(AuNRs)based intelligent composite nanogels are the intelligent nanomaterials which combine the unique properties of both AuNRs and intelligent nanogels.Their prominent characteristic is that a variety of properties of the loaded AuNRs within the nanogels can be tuned by external stimulus,or external stimulus can be sensed by determining the change of their properties.The characteristics and synthesis methods of AuNRs based intelligent composite nanogels of three kinds of morphological structure including core-shell structure type,randomly filling type,strawberry structure type are firstly reviewed in this paper.Then,the properties and applications of AuNRs based intelligent composite nanogels are summarized.Finally,their future research direction and development outlook are commented.
