65438+1The paper published in Nanocommunication on October 5th shows that Chinese researchers have processed bacterial cellulose (BC) hydrogel into hydrogel fiber (BHF) with lotus-like micro-helix structure, which has high strength and toughness, and excellent hydrophilicity and biocompatibility.
The bionic spiral structure also gives the material elasticity similar to human skin. When the wound is deformed, BHF can effectively buffer and absorb energy, realize synchronous deformation with human tissue, and avoid secondary injury caused by cutting the wound.
Compared with traditional cotton thread or polymer thread, hydrogel fiber suture has the characteristics of high biocompatibility, high water content, low irritation and low friction resistance, and has obvious advantages in protecting damaged tissues, promoting wound healing and reducing adverse reactions, so it is expected to become the next generation of new high-end surgical suture.
It is reported that the three-dimensional nanofiber network of bacterial cellulose hydrogel makes BHF have high strength exceeding 90 MPa. Its unique cellulose nanofiber network and bionic spiral structure bring uniqueness? Stretchable, inelastic? Its mechanical properties lay a good foundation for its application in the field of high-end surgical suture.
In addition, the porous structure of nanofiber hydrogel also enables BHF to adsorb antibiotics or anti-inflammatory drugs and release them continuously at the wound, thus playing the role of anti-inflammation and accelerating wound healing. Based on this bionic design, BHF is expected to show its unique application potential in more fields of medical materials. It is reported that the patents related to this material have been approved and authorized. ?
It can be seen that the functions and benefits of this new material are very obvious, especially in the fields of surgery and biology. The characteristics of this surgical suture are very prospective. I believe that with the continuous improvement and extension of scientists, there will be more breakthroughs and uses. At this point, in fact, compared with 20 10, China's scientific research level has made great progress and promotion.
However, this scientific research result is also produced by scientists? Break off the relationship? I believe that there will be more and more scientific research achievements like this in the future. After all, at present, China has invested a lot in scientific research, and the strategy of strengthening the country through science and technology has been supporting many scientists to invest in the cause of building the motherland. The future is expected.
