More information sabine rosenfeldt et al towards standardized purification of bacterial magnetic nanoparticles for future in vivo applications acta biomaterialia 2020 doi 101016 jactbio . Abstract in this chapter we present the design fundamentals on the development of magnetic nanoparticle systems to become suitable for biomedical applications from the most used strategies for chemical synthesis and surface functionalization to their main researched applications in the biomedical field nowadays. Biomedical applications of magnetic nanoparticles 1641 cellular labeling cell separation ferro paramagnetic materials are used for cell labeling that allows the 1642 detoxification of biological fluids mnps are coated with antibodies against antigens for epithelial cell 1643 tissue . Magnetic nanoparticles nps are emerging as an important class of biomedical functional nanomaterials in areas such as hyperthermia drug release tissue engineering theranostic and lab on a chip due to their exclusive chemical and physical properties although some works can be found reviewing the main application of magnetic nps in the area of biomedical engineering recent and intense progress on magnetic nanoparticle research from synthesis to surface functionalization
