چکیده

در سال‌های اخیر حضور مواد بر پایه گرافن مانند اکسید گرافن به دلیل دارا بودن ویژگی‌های منحصر به‌فردی رشد چشم‌گیری در حوزه پزشکی داشته است. در این تحقیق نانوکامپوزیت اکسید گرافن- مگنتیت با قابلیت رهایش کنترل شده دارو به روش سنتز هم‌رسوبی روی لایه‌های اکسید گرافن تولید شد. مطالعات فازی، مورفولوژی ذرات، خواص مغناطیسی و بارگذاری و رهایش دارو به‌ترتیب به روش‌های XRD، FE-SERM، VSM و طیف‌سنجی ماوراء بنفش-مرئی مورد بررسی قرار گرفت. طرح پراش اشعه ایکس شکل‌گیری مگنتیت و اکسید گرافن را در این کامپوزیت نشان داد. بررسی‌های میکروسکوپ الکترونی روبشی مشخص کرد اندازه متوسط ذرات مگنتیت سنتز شده 14 نانومتر است. مغناطش اشباع برای نانوکامپوزیت اکسید گرافن- مگنتیت emu/g 47 بود و این نانوکامپوزیت رفتار سوپر-پارامغناطیس از خود نشان داد. داروی دوکسوروبیسین هیدروکلراید روی این نانوکامپوزیت بارگذاری شد. بررسی‌های بارگذاری و رهایش دارو نشان داد که بازده کپسوله کردن و درصد بارگذاری دارو روی این سامانه به‌ترتیب 51/76% و 34/68% است. مدل رهایش این دارو مدل کورسمایر- پپاس تشخیص داده شد.

چکیده [English]

Graphene based materials such as graphene oxide have been developed in the biomedical applications during recent years. In this research, graphene oxide/magnetite nanocomposite with drug controlled release ability was synthesized through coprecipitation on graphene oxide sheets. Phase analysis, particles morphology, magnetic properties, drug loading and release behavior of the synthesized nanocomposite was investigated using XRD, FESEM, VSM and UV-visible spectroscopy, respectively. XRD pattern showed formation of the graphene oxide/magnetite nanocomposite. FESEM images revealed that the mean particles size is 14 nm. The synthesized nanocomposite showed superparamagnetic characteristics while the saturation magnetization of the nanocomposite was 47 emu/g. Doxorubicin hydrochloride as an anti-cancer drug was loaded on the nanocomposite. Encapsulation efficiency and loading of the drug for the nanocomposite were 51.76% and 34.68%, respectively. The release model of the drug was best matched with Korsmeyer-Peppas model.
