  • How are sodium alginate-polyacrylamide hydrogels synthesized?
  • Sodium alginate-polyacrylamide (SA-PAM) hydrogels were synthesized by a combination of chemically cross-linked with acrylamide and ion crosslinked by divalent cations (copper, zinc, strontium, and calcium) [ 89 ]. The introduction of divalent ions improved mechanical property while reduced the swelling ratio and pore size.
  • Can ionically crosslinked sodium alginate hydrogel be used for wound healing?
  • Covalently crosslinked PVA and ionically crosslinked sodium alginate were combined into a hybrid hydrogel, The incorporation of laponite improved its mechanical properties and increased blood coagulation. This alginate hydrogel can be an ideal hydrogel for wound healing applications [90 ].
  • Is alginate a polysaccharide?
  • Alginate is a natural linear polysaccharide derived from brown algae or bacteria, consisting of repeating units of β-1,4-linked D-mannuronic acid (M) and L-guluronic acid (G) in different ratios. It is widely used in biomedical and engineering fields due to its good biocompatibility and liquid absorption capacity.
  • How is alginate a covalent hydrogel?
  • Alginate has functional groups such as -COOH or -OH, and thus can be used for the formation of covalent hydrogels. Covalently crosslinked alginate hydrogels can be synthesized via various reactions, including polymerization, addition, click chemistry, or high energy irradiations (gamma-ray or electron beam).
