Abstract
Elektro-eğirme metodu gelişmiş üretim teknolojilerindendir ve biyomedikal uygulamalarında yaygın
olarak kullanılmaktadır. Özellikle doku mühendisliğinde amaç, çalışılacak doku üzerine doğal veya sentetik destek materyali (iskele) üreterek hücrenin uyum sağlayabileceği bir ortam oluşturmaktır. Bu projenin amacı üç boyutlu (3D) hücre kültürü çalışmaları için elektro-eğirme-metodu ile
poli(L-laktik-co-epsilon-kaprolakton) (PLLCL) kullanılarak iskele üretilmesidir. Homojen lifler ve uygun gözenek boyutu elde etmek amacıyla optimizasyon çalışmaları yapılmıştır. Elde edilen liflerin çapı, akış hızı ve voltajın artmasıyla azalmaktadır. Taramalı uç elektron mikroskop incelemeleri (SEM) lif morfolojik yapılarının doku iskelesi fabrikasyonu için ideale yakın olduğunu ortaya çıkarmıştır.
Electrospinning method is one of the advanced manufacturing technologies that widely used in biomedical applications. Especially the aim of tissue engineering is to fabricate naturally or synthetic support material (scaffold) for a tissue which is studied to provide suitable environment for cells. The aim of the project is producing poly (L-lactide-co-epsilon-caprolactone) (PLLCL) nanofibers as a scaffold by using electrospinning method in order to three dimensional (3D) cell cultures studies. Optimization studies were made in order to obtain homogeneous fibers and suitable pore size. The obtained fibers diameter decreases by increasing flow rate and voltage. By scanning electron microscopy (SEM) morphological structures of fibers examined that exhibiting nearly perfect conditions for scaffold.
