应用
This product is a low endotoxin version alginate methacrylate ready to be used in biomedical applications.
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. Alginate hydrogels are commonly used to fabricate tissue engineering scaffolds, bioinks for 3D bioprinting, and nanocarriers for drug & gene delivery. Due to the thermal or photochemical crosslinking of the terminal methacrylates, methacrylate-functionalized alginate can be used to prepare hydrogels resistant to matrix degradation. Properties of the resulting hydrogel (e.g., stiffness, swelling ratio, rate of degradation) can be tuned by alginate molecular weight, degree of methacrylate functionalization, and crosslink density.

In situ photopolymerization is an exciting new technique for tissue engineering. Two photocrosslinkable polysaccharides composed of alginate and hyaluronan are described that upon photolysis form soft, flexible, and viscoelastic hydrogels. The degree of methacrylate modification and thus covalent affects mechanical

Recent advances in three-dimensional (3-D) printing offer an excellent opportunity to address critical challenges faced by current tissue engineering approaches. Alginate hydrogels have been used extensively as bioinks for 3-D bioprinting. However, most previous research has focused on native alginates
