Synthesis and characterization of PVA/Dextran Hydrogel for application indrug delivery

Effective drug uptake by target issues is one of the main concerns for medical researchers. Hydrogels areconsidered as a group of polymers with the ability to absorb and release substance. They are made of easilyaccessible Nontoxic and Eco-friendly materials. The purpose of present study is the synthesis and characterizationof hydrogel made from Poly Venial Alcohol /dextran (PVA/Dex) by freeze – thaw method in different volumeratios. Characterization trials were carried out by SEM, FT-IR and many other methods.
