چکیده
Cancer is one of the biggest diseases that kill a lot of people in the entire world. Even withdevelopment of different pharmaceutical agents, this disease is one the biggest challenge inscience. So, investigation for development of new compounds for cancer therapies is veryactive. In between, nanostructures such as carbon nanotubes were considered recently. Theaim of this study is investigation of anticancer activity of pristine and functionalizedmultiwalled carbon nanotubes with basic amino acids, lysine and arginine. Multi-walledcarbon nanotubes (MWCNTs) were first functionalized by arginine and lysine undermicrowave radiation. Surface functionalization was confirmed by Fourier transform infrared(FTIR) spectroscopy, Raman spectroscopy, and transmission electron microscopy (TEM).After the MWCNTs were functionalized by arginine and lysine, the cytotoxic effect of pristineand functionalized MWCNTs on breast cancer cell line (T47d) was investigated. Anticanceractivity of all treated samples was observed significantly against examined cancerous cellline. Based on the observed results, the sequence of activity was MWCNTs-arginine > MWCNTs-lysine > pristine MWCNTs. The functionalized MWCNTs were especially moreeffective against cell growth than pristine MWCNTs. Due to high negative charge ofcancerous cell, the enhanced anticancer activity of functionalized MWCNTs was attributed toelectrostatic adsorption of cancerous cell due to positive charges of the functional groups onMWCNTs surface. In this study, it observed a significant decrease in cell survival in cellstreated with the functionalized MWCNTs by arginine and lysine in compared with pristineMWCNTs.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.
