受Matthias Ballauff过去20年所走过的道路的启发，回顾了热敏核壳微凝胶结构的发展。许多不同的团队已经设计并成功实现了从硬纳米颗粒核心到双刺激响应微凝胶的不同化学结构。介绍了这些系统的一些丰富种类，以及通过中子或 X 射线小角散射对此类微观结构进行结构分析的一些最新进展，包括建模方法。在最后一部分中，再次遵循 Matthias Ballauff 小组的早期工作，将讨论特别强调在核-壳结构内掺入催化纳米粒子（稳定纳米粒子并给予对活性的外部控制）的应用，以及界面处的核-壳微凝胶。
Inspired by the path followed by Matthias Ballauff over the past 20 years, the development of thermosensitive core-shell microgel structures is reviewed. Different chemical structures, from hard nanoparticle cores to double stimuli-responsive microgels have been devised and successfully implemented by many different groups. Some of the rich variety of these systems is presented, as well as some recent progress in structural analysis of such microstructures by small-angle scattering of neutrons or X-rays, including modelling approaches. In the last part, again following early work by the group of Matthias Ballauff, applications with particular emphasis on incorporation of catalytic nanoparticles inside core-shell structures-stabilising the nanoparticles and granting external control over activity-will be discussed, as well as core-shell microgels at interfaces.
