In addition, the bionic spiral structure endows the material with 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, laying 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. At present, the related patents of this material have been approved and authorized.
Besides the bionic surgical suture inspired by lotus root, what other successful examples are there? Flies and spacecraft, from annoying flies, successfully copied a very strange small gas analyzer, which was installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin. The windward ear of jellyfish imitates the structure and function of jellyfish ear, and designs a storm predictor of jellyfish ear, which can predict the storm 15 hours in advance, which is of great significance to navigation and fishery safety. Colorful butterflies, such as bimonthly butterflies and monarch butterflies with brown veins, especially butterflies with fluorescent wings, will turn into gold, green and blue in the sun. Scientists have brought great benefits to military defense by studying the color of butterflies. This paper points out that the color of butterflies is not easy to be found in flowers, and military facilities are covered with butterfly-like camouflage. So according to the same principle, people later produced camouflage clothes.
