Abstract
Cellulose is the carbohydrate polymer composed of carbon, hydrogen and β-glucose, and the main composition of plant cell walls. The aim of this study is to evaluate the effect and potential of 1-2 MeV electron beam (E-beam) irradiation to the sea squirt derived cellulose membrane (CM) from Styela clava, called non-native tunicate. C-O bonding was increased than C-C bonding, and several related results showed depolymerization of cellulose microfibrils composed of microtubles. Cross-linking cellulose protein (CCP) was lost after E-beam irradiation, and so thin and delicate cellulose fibrils were detached each other by moving cellulose synthase complex. The potential of this cellulose polymer as a thin μm thickness medical membrane for the guided bone regeneration can be suggested.

셀룰로오스는 탄소와 수소 성분으로 이루어진 탄수화물 복합체로서 β-글루코오스 성분으로 이루어진 식물 세포벽의 주된 구성성분이다. 미더덕의 피부 각질에서 개발한 동물성 셀룰로오스 유도막에 1-2 MeV 에너지의 전자빔을 조사하여 C-C 결합보다 C-O 결합이 보다 증가함을 확인하였고, 여러 관련된 결과를 바탕으로 전자빔 조사에 의해 미세소관을 구성하는 셀룰로오스 미세원섬유들의 탈중합 과정을 일으킬 수 있었다. 셀룰로오스 합성복합체가 이동함으로써 셀룰로오스 섬유소들을 균일하고 미세하게 변형시킴으로써 골유도재생술을 위한 얇은 μm 단위의 의료용 유도막으로 활용이 가능할 것으로 사료된다.
