چکیده
|
The magnetic fe-mbg/c composite scaffolds with enhanced mechanical strength and multifunctionality have been successfully prepared. the study showed that the fe-mbg/c composite scaffolds with the porosity of ca. 80% had interconnected macropores (200-500 μm) and mesopores (3.7-4.4 nm) and significantly enhanced the compressive strength compared to the pure mbg scaffolds. importantly,the fe-mbg/c composite scaffolds exhibited good bioactivity and sustained drug release property. at the same time,the fe-mbg/c composite scaffolds could generate heat to raise the temperature of surrounding environment in an alternating magnetic field due to their superparamagnetic behavior. therefore,the magnetic fe-mbg/c composite scaffolds could form a multifunctional platform with bone regeneration,magnetic hyperthermia,and local drug delivery and have more potential for use in the regeneration of the critical-sized bone defects caused by bone tumors. © 2013 min zhu et al.
