Application
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

Alginates have become an extremely important family of polysaccharides because of their utility in preparing hydrogels at mild pH and temperature conditions, suitable for sensitive biomolecules like proteins and nucleic acids, and even for living cells such as islets of

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

Photocrosslinked and biodegradable alginate hydrogels were engineered for biomedical applications. Photocrosslinkable alginate macromers were prepared by reacting sodium alginate and 2-aminoethyl methacrylate in the presence of 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride and N-hydroxysuccinimide. Methacrylated alginates were photocrosslinked using ultraviolet light with 0.05% photoinitiator.

Methods for seeding high-viability (>85%) three-dimensional (3D) alginate-chondrocyte hydrogel scaffolds are presented that employ photocrosslinking of methacrylate-modified alginate with the photoinitiator VA-086. Comparison with results from several other photoinitiators, including Irgacure 2959, highlights the role of solvent, ultraviolet exposure, and
