Web14 Mar 2024 · Chitosan is often used in the form of composites (with the participation of ceramic particles), membranes, hydrogels or nanoparticles. The problem with biomaterials is their low durability, rapid degradation, poor mechanical properties and cytotoxicity. Cross-linking or stabilization of such materials allows for solving these problems. WebIonically crosslinked chitosan membranes were prepared and their density was determined using modified pycnometer method. High‑molecular compound: sodium alginate (NaAlg) and low‑molecular compounds: pentasodium tripolyphosphate (TPP) and trisodium citrate (CIT) were used as ionic crosslinkers of chitosan. gwyneth paltrow sapphire engagement ring https://cortediartu.com
