Abstract
One of the most attractive features of magnetic ferrite nanoparticles (MFNPs) in biomedical application is that they can mediate external magnetic field to produce local magnetic field, magnetic thermal and magnetic force effects. These generated effects can later be utilized in the diagnosis and treatment of various diseases. The application performance is mainly determined by the nano-magnetism of MFNPs. Therefore, by modulating the magnetic properties, the improved magnetic resonance (MR) signals, magnetothermal, and magnetomechanical effects of the MFNPs can be achieved. In this review, we summarize the strategies used in the engineering of MFNPs to enhance MR imaging sensitivity and magnetic thermal conversion efficiencies. We will also discuss the detailed magnetoresponsive mechanism arising from the critical magnetic properties of MFNPs. Furthermore, we will highlight the recent progresses of the engineered MFNPs in biomedical applications, with emphasis in MR signal amplification, magnetothermal, and magnetomechanical response in biomedical applications.
