“…19,20 It usually used template 21 or etching method 22 for fabrication of porous materials, however, the reaction process was complex and poorly controllable. Interestingly, researchers achieved iron oxide microparticles possessing high magnetic permeability, high saturation magnetization and low coercivity 23 by designing their chemical components and modulating their size 24 and shape, 25 which have the potential to signicantly improve heating conversion efficiency. 26,27 In this study, rugby ball-shaped magnetic microcapsules with superior heating conversion efficiency were prepared for MH-triggered cancer treatment.…”
