The Preparation of Chitosans Membranes with Different Molecular Weight

Objective Growth factors are used to accelerate osseous integrations.Usually,growth factors are destroyed easily and fixed difficultly in oral implantology area.The aim of this study was to prepare chitosans membrane with different molecular weight,and provide evidence for the application of chitosans in oral implants.Method Chitosans membranes and gelatin-chitosans membranes were prepared with chitosans with different molecular weight(3 000,100,000,200,000,450,000)by solvent evaporation method.Results Chit...
