Abstract:
BACKGROUND: In recent years, nanoparticles has been rapidly developing in tumor hyperthermia, genophore research, and targeted drug therapy, particularly nanoparticle containing drug delivery systems will become another breach in tumor therapy.OBJECTIVE: To summarize the application and mechanism of superparamagnetic nanoparticles for cancer treatment in the medical field.METHODS: A computer-based online search was conducted in Medline for English language publications containing the key words of "superparamagnetic, nanoparticles, targeting" from January 2000 to October 2009. Relevant articles were also searched from CNKI with the same key words in Chinese from January 2005 to October 2009.RESULTS AND CONCLUSION: A total of 123 articles about targeting role of magnetic nanoparticles were included, and there were 24 in Chinese and 108 in English. Articles published earlier, duplicated, and similarly were excluded, and 30 references were finally included. Superparamagnetic nanoparticles characterized by targeting role under external magnetic field, and crystal of ferroso-ferric oxide did not has toxicity to cells. As a gene carrier and drug carrier, superparamagnetic nanoparticles were widely used in medical research and they also provided novel evidences for cancer treatment. By an external magnetic field, how to avoid a comprehensive system of phagocytic endothelial phagocytosis and prevent the course of treatment such as drug-induced thrombus is still inadequate.
