The development of advanced materials relies on an innovative combination of two completely different materials. Loading quantum dots (QDs) into a three-dimensional (3D) network of hydrogels has proved to be a win-win strategy to enhance the synergy of the components. The resulting new QDs/hydrogel composites have a wide range of applications in important fields such as health, energy and environment. Herein, we review recent research progress of QDs/hydrogel composites. Synthetic strategies are classified into different categories according to the preparative sequence, a relatively more practical perspective, between the QDs and hydrogel. In addition, we summarize the latest applications of these nanocomposites (NCs) in the sensing field, with a focus on fluorescence sensing. We hope that this review can provide the reader with a comprehensive understanding on this composite system quickly so that they can choose the most suitable preparation method or sensing scheme based on actual conditions and requirements to obtain QDs/hydrogel composites with optimal performance.

用于传感应用的基于量子点的水凝胶

先进材料的开发依赖于两种完全不同的材料的创新组合。将量子点(QD)加载到水凝胶的三维(3D)网络中已证明是增强组件协同作用的双赢策略。所得的新型量子点/水凝胶复合材料在健康,能源和环境等重要领域具有广泛的应用。在此,我们综述了量子点/水凝胶复合材料的最新研究进展。根据量子点和水凝胶之间的制备顺序(相对更实际的观点),合成策略分为不同类别。此外,我们总结了这些纳米复合材料(NCs)在传感领域的最新应用,重点是荧光传感。
