چکیده
Introduction: Breast cancer is the most common form of cancer (other than skin cancer) in women. 200,000 new cases of breast cancer detected each year of which40,000 will die. Nanotechnology has provided an alternative strategy of drug delivery to prevent drug efflux by offering encapsulation or attachment of drugs tonanomaterials such as lipids, polymers and solid-core nanoparticles. Methods: Iron oxide nanoparticles were prepared by using a conventional coprecipitation method and coated with silica using a sol−gel method to afford core-shell magnetic nanoparticles. Folic acid as a targeting agent was activated and attached to Polyethyleneimine. The polymer obtained was coated on magnetic cores. The core-shell nanoparticles were characterized by different methods. Doxorubicin was loaded into the nanoparticles andthe realese behavior was studied in different pH conditions. Results: Doxorubicin loading 54.6% was obtained and released drug in acidic pH was obviously more than physiologic pH. Conclusion According to the results we can optimize our core-shell nanostructure as an efficient drug delivery carrier as well as MRI contrast agent for breast cancer.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
