|Title:||Foaming Alginate For Tissue Engineering|
|Abstract:||Alginates are linear unbranched polysaccharides containing beta-(1-1) linked D-mannuronic acid and alpha-(1-4) linked L-guluronic acid. The alginate hydrogels are produced by mixing the alginate with a proper crosslinking agent. During the gel formation, crosslinks between alginate chains and cationic species are formed, changing the elastic behaviour of the material controlling the volume change phenomena of gels. This research study focuses on a new route to produce three-dimensional patterns (or scaffolds) in alginate hydrogels for tissue engineering applications. This process involves a generation of foams from a network calcium alginate polymer by lyophilisation. Different structures were produced using different alginate compositions. It was observed that the alginate composition determines both the rheological characteristics of the solution and the morphological characteristics of the scaffolds. © 2008 Taylor & Francis Group.|
