The hierarchically structured core-shell magnetic mesoporous silica nanospheres (Mag-MSNs) have attracted extensive attention, particularly in studies involving reliable preparations and diverse applications of the multifunctional nanomaterials in multi-disciplinary fields. Intriguingly, Mag-MSNs have been prepared with well-designed synthesis strategies and used as adsorbent materials, biomedicines, and in proteomics and catalysis due to their excellent magnetic responsiveness, enormous specific surface area and readiness for surface modifications. Through a carefully designed surface modification of Mag-MSNs, the performance and application prospects of the material are greatly improved. Typically, the introduction of various molecular matrices into the shell of Mag-MSNs facilitates the combination of surface modifications and magnetic separation technology. So far, as sustainable chemistry is concerned, it is important to recover the functionalized core-shell Mag-MSNs after the reaction and reuse them without losing activity. In this review, the design conceptions and the construction of core-shell Mag-MSNs are discussed. Furthermore, various surface modification approaches of core-shell Mag-MSNs are summarized, and recent applications of these functionalized nanomaterials in the fields of biomedicine, catalysis, proteomics and wastewater treatment are exemplified.

核-壳磁性介孔二氧化硅纳米球的合成，表面改性及其应用的最新进展。

分层结构的核-壳磁性介孔二氧化硅纳米球（Mag-MSNs）引起了广泛的关注，特别是在涉及可靠制备和多功能纳米材料在多学科领域的各种应用的研究中。有趣的是，Mag-MSNs具有精心设计的合成策略，由于其出色的磁响应性，巨大的比表面积和易于表面修饰的特性，已被用作吸附材料，生物医学以及蛋白质组学和催化领域。通过精心设计的Mag-MSNs表面改性，极大地提高了材料的性能和应用前景。通常，在Mag-MSN的外壳中引入各种分子基质，有助于表面修饰和磁分离技术的结合。迄今为止，就可持续化学而言，重要的是在反应后回收官能化的核壳型Mag-MSN，并在不损失活性的情况下对其进行再利用。在这篇综述中，讨论了核壳型Mag-MSN的设计概念和构造。此外，总结了核-壳型Mag-MSN的各种表面修饰方法，并举例说明了这些功能化的纳米材料在生物医学，催化，蛋白质组学和废水处理领域的最新应用。重要的是在反应后回收官能化的核-壳型Mag-MSN，并在不损失活性的情况下重复使用它们。在这篇综述中，讨论了核壳型Mag-MSN的设计概念和构造。此外，总结了核-壳型Mag-MSN的各种表面修饰方法，并举例说明了这些功能化的纳米材料在生物医学，催化，蛋白质组学和废水处理领域的最新应用。重要的是在反应后回收官能化的核-壳型Mag-MSN，并在不损失活性的情况下重复使用它们。在这篇综述中，讨论了核壳型Mag-MSN的设计概念和构造。此外，总结了核-壳型Mag-MSN的各种表面修饰方法，并举例说明了这些功能化的纳米材料在生物医学，催化，蛋白质组学和废水处理领域的最新应用。
