Magnetic Janus particles (MJPs) with compositional compartmentalization and strong magnetic responsiveness play a pivotal role in various application fields, such as biotechnology, medicine, and materials science. However, comprehensive reviews of the field of MJPs remain limited. Here, this article attempts to fill the gap by reviewing the current common synthetic strategies for MJPs, including masking, microfluidics, self-assembly, phase separation, and seeded emulsion polymerization, among others. It then covers the multifunctional applications of MJPs, beneficial from their magnetic properties and anisotropic topological structure, primarily involving environmental remediation, biomedicine, smart displays, interfacial catalysis, emulsion stabilization, and structured liquid materials are presented, as well. Finally, the current challenges and future perspectives for MJPs are also discussed, aiming to fully harness the potential for broader applications.
具有成分分区和强磁响应性的磁性Janus粒子（MJPs）在生物技术、医学和材料科学等各种应用领域中发挥着关键作用。然而，对MJPs领域的全面综述仍然有限。在此，本文试图通过回顾当前MJPs常见的合成策略来填补这一空白，这些策略包括掩蔽法、微流控法、自组装法、相分离法和种子乳液聚合法等。接着介绍了MJPs的多功能应用，这些应用得益于其磁性和各向异性拓扑结构，主要涉及环境修复、生物医学、智能显示、界面催化、乳液稳定和结构化液体材料等方面。最后，还讨论了MJPs目前面临的挑战和未来前景，旨在充分挖掘其在更广泛应用中的潜力。
