CELLULOSE GEL FOR BIOMEDICAL APPLICATION

Abstract

Cellulose gel was prepared by the sol-gel method based on cellulose regeneration from its acetylated derivatives. The mechanical characteristics of the gel were foud depend on gel formation conditions. Heparinization of the gel surface was performed by three different methods. The gel antithrombogenic properties of the gel were foun to depend on the amount of coupled heparin. Blood coagulation on a heparinized surface is slower and takes about 16 hours.
