چکیده
Nanofibrous mats of two biopolymers, poly(lactic acid) (PLA) and gelatin, were prepared by electrospinning. Morphology of the mats was investigated by Scanning Electron Microscopy (SEM) and their nanofibrous structure was confirmed. Gelatin nanofibers were crosslinked using a crosslinking agent and their change in morphology was investigated by SEM, too. Nanofibrous structure of gelatin nanofibers was lost to high extent by crosslinking. Biodegradation of nanofibers in Phosphate buffered saline (PBS) solution was evaluated and SEM images showed that PLA nanofibers degraded very slowly but gelatin nanofibers were completely dissolved and should be crosslink to prevent dissolving in aqueous medium.کلیدواژه ها

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.
