“…With the development of the modern science, it is a great challenge to develop approaches to synthesize magnetic particles with suitable size, which helps to meet special need of biomedical fields. The research results indicate that various magnetic nano-or microparticles have been considered as ideal candidates for biological applications, such as protein and enzyme immobilization, cell isolation, DNA and RNA purification, immunoassay and guided site-specific drug delivery, [16][17][18][19][20] due to their good hydrophilic and biocompatible properties.…”
