Cancers are fatal diseases that lead to most death of human beings, which urgently require effective treatments methods. Hyperthermia therapy employs magnetic nanoparticles (MNPs) as heating medium under external alternating magnetic field. Among various MNPs, ferrite nanoparticles (FNPs) have gained significant attention for hyperthermia therapy due to their exceptional magnetic properties, high stability, favorable biological compatibility, and low toxicity. The utilization of FNPs holds immense potential for enhancing the effectiveness of hyperthermia therapy. The main hurdle for hyperthermia treatment includes optimizing the heat generation capacity of FNPs and controlling the local temperature of tumor region. This review aims to comprehensively evaluate the magnetic hyperthermia treatment (MHT) of FNPs, which is accomplished by elucidating the underlying mechanism of heat generation and identifying influential factors. Based upon fundamental understanding of hyperthermia of FNPs, valuable insights will be provided for developing efficient nanoplatforms with enhanced accuracy and magnetothermal properties. Additionally, we will also survey current research focuses on modulating FNPs' properties, external conditions for MHT, novel technical methods, and recent clinical findings. Finally, current challenges in MHT with FNPs will be discussed while prospecting future directions.
癌症是导致人类死亡的主要疾病,迫切需要有效的治疗方法。热疗采用磁性纳米粒子(MNPs)作为外部交变磁场中的加热介质。在各种 MNPs 中,由于其优异的磁性能、高稳定性、良好的生物相容性和低毒性,铁氧体纳米粒子(FNPs)在热疗中引起了广泛关注。FNPs 的利用为提高热疗的效果提供了巨大的潜力。热疗的主要障碍包括优化 FNPs 的发热能力和控制肿瘤区域的局部温度。本综述旨在全面评估 FNPs 的磁热疗(MHT),通过阐明发热的潜在机制和确定影响因素来实现。基于对 FNPs 热疗的基本理解,将为开发具有增强准确性和磁热性能的高效纳米平台提供有价值的见解。此外,我们还将调查当前研究重点是调节 FNPs 的性质、MHT 的外部条件、新的技术方法和最近的临床发现。最后,将讨论 MHT 中使用 FNPs 所面临的挑战,同时展望未来的方向。
