“…Moreover, a more pronounced effect was observed when cross-linked with EDC/NHS. Similar results were reported for the cross-linking of kaolin (K) into carboxymethyl chitosan (CMCS)/SA and collagen from a bovine Achilles tendon, using oxidized multi-walled carbon nanotubes with riboflavin sodium phosphate [30,31]. The presence of proteinaceous components in (c), (d), and (e) is evident from the FTIR spectra, where the bands at 1653 cm −1 and 1558 cm −1 can be assigned to amide I and II, respectively [32].…”

(1) Background: Collagen and sodium alginate are commonly used in the field of biomedical materials due to their excellent biocompatibility. This study focuses on the preparation, modification, and characterization of collagen/sodium alginate (C/SA)-based biomedical materials. (2) Methods: The characteristics, including surface chemistry, mechanical properties, hygroscopicity, and porosity, were analyzed. The hemostatic activity in vitro was measured using a blood clotting assay and dynamic blood clotting assay. (3) Results: The results from microstructure and porosity measurement revealed that all of the sponges exhibited a porosity of more than 95 percent. The sponge cross-linked with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide (EDC/NHS) showed better tensile strength and lower elongation at break. The sponges cross-linked with EDC/NHS and oxidized sodium alginate (OSA) exhibited the highest hygroscopicity in comparison with the uncross-linked sponge. (4) Conclusions: Our study demonstrated that the C/SA-based material we prepared exhibited a high level of porosity, enabling efficient absorption of tissue exudate and blood. Additionally, the materials revealed excellent hemocompatibility, making them suitable for use as a hemostatic dressing in the field of biomedical materials.

“…76 Recently, Henao et al used sodium riboflavin phosphate to modify multilayer carbon nanotubes and cross-link them with collagen to synthesize photosensitive collagen nanocomposites, and the results showed that MWCNT-riboflavin (MW FMN ) nanoparticles improved the structural and thermal properties of the collagen matrix. 77 CD NPs have low cytotoxicity and good biocompatibility and can be applied as nanomaterials to enhance the mechanical stability of collagen hydrogels. Many researchers have shown that CD NPs can be applied as photosensitizers for photodynamic therapy (PDT), generating reactive oxygen species (ROS).…”

Cartilage regeneration remains difficult due to a lack of blood vessels. Degradation of the extracellular matrix (ECM) causes cartilage defects, and the ECM provides the natural environment and nutrition for cartilage regeneration. Until now, collagen hydrogels are considered to be excellent material for cartilage regeneration due to the similar structure to ECM and good biocompatibility. However, collagen hydrogels also have several drawbacks, such as low mechanical strength, limited ability to induce stem cell differentiation, and rapid degradation. Thus, there is a demanding need to optimize collagen hydrogels for cartilage regeneration. In this review, we will first briefly introduce the structure of articular cartilage and cartilage defect classification and collagen, then provide an overview of the progress made in research on collagen hydrogels with chondrocytes or stem cells, comprehensively expound the research progress and clinical applications of collagen‐based hydrogels that integrate inorganic or organic materials, and finally present challenges for further clinical translation.
