陶瓷微球有望用于癌症治疗和抗菌治疗。在本文中，描述了为此类生物医学应用制备陶瓷微球的几种尝试。含有大量钇或磷的陶瓷微球可用于癌症的放射治疗，因为它们可以通过中子轰击被激活成为磷发射体。亚铁磁微球可用作癌症热疗的热种子，因为它们可以通过亚铁磁材料在交变磁场下的磁滞损耗来局部加热癌症。当与有机聚合物，特别是细纺聚合物纤维混合时，含银二氧化硅玻璃微球可用作抗菌材料。
Cera-mic microspheres are expected to be useful for cancer treatment and antibacterial treatment. In this article, several attempts to prepare ceramic microspheres for such biomedical applications are described. Ceramic microspheres containing large amounts of yttrium or phosphorus are useful for radiotherapy of cancers, since they can be activated to become P-emitters by neutron bombardment. Ferrimagnetic microspheres are useful as thermoseeds for hyperthermia of cancers because they can heat cancers locally by hysteresis loss of the ferrimagnetic materials under an alternating magnetic field. Silver-containing silica glass microspheres are useful as antibacterial materials when mixed with organic polymers, particularly fine-spun polymer fibers.
