Aplicação
Alginate is an anionic polysaccharide that is widely used in pharmaceutical and biomedical applications due to its non-animal origin, low toxicity, biocompatibility, and biodegradability[1]. Alginate hydrogels are commonly used to fabricate tissue engineering scaffolds[2], bioinks for 3D bioprinting[3][4], and nanocarriers for drug and gene delivery.
Alginate is commonly crosslinked into a hydrogel via ionic-crosslinking with divalent cations (e.g., Ca2+). To prevent matrix degradation, alginate can be functionalized with reactive groups that can be chemically crosslinked, such as aldehydes.[5] Aldehyde- functionalized alginate can be used to prepare hydrogels by reaction with amine groups, such as gelatin through Schiff-base reaction to form a chemical hydrogel. This material can be used in a variety of biomedical applications such as the delivery of drugs, cells, or biomolecules in different tissues, wound healing, and muscle and bone tissue engineering.

Periodate oxidation of sodium alginate in aqueous solution as well as a dispersion in 1:1 ethanol-water was examined. The oxidation proceeded smoothly in both media, and the kinetics of oxidation was surprisingly similar. Polymer cleavage was observed in both media

The injectable polymer scaffolds which are biocompatible and biodegradable are important biomaterials for tissue engineering and drug delivery. Hydrogels derived from natural proteins and polysaccharides are ideal scaffolds for tissue engineering since they resemble the extracellular matrices of the tissue

Is the alginate aldehyde terminated, as described in the linear formula, with only 20% of the chains functionalized? Or is the backbone of the chain functionalized with aldehyde with 20% of the monomers containing aldehyde groups?
