Problems solved by technology

Moreover, excessive ROS can lead to dysfunction of related cells such as endogenous stem cells, endothelial cells, and macrophages, inhibit angiogenesis, and hinder wound tissue healing.
However, the current wound dressings cover the wound surface, so it is impossible to visually see the healing of the wound surface, and the antibacterial performance is limited, so it cannot meet the actual needs

Embodiment 1

[0043] Preparation of anthocyanin-metal ion coordination compound: 0.5 g of anthocyanin and 0.5 g of zinc chloride (ZnCl 2 ) solution was dissolved in 30 mL and 10 mL of deionized water respectively; stirred at room temperature for a period of time until the anthocyanin was completely dissolved, then 0.1 mL of ammonia water (28wt%) was added dropwise to the anthocyanin solution; continued stirring for 5min, the ZnCl 2 The solution is slowly added dropwise to the alkaline anthocyanin solution, and a large amount of precipitation will be produced immediately at this time; continue to stir for 10 minutes, then centrifuge at 5000 rpm for 10 minutes, then wash with deionized water, repeat 3 times; freeze-dry the product obtained by centrifugation to obtain flower The cyanine-zinc ion coordination compound, the scanning electron microscope image of its microscopic morphology is as follows figure 1 shown.

Embodiment 2

[0046] The difference between embodiment 2 and embodiment 1 is that copper chloride (CuCl) is used in embodiment 2. 2 ) replace the zinc chloride (ZnCl 2 ), and other preparation processes were the same as in Example 1. The finished product 2 of the multifunctional fiber dressing was prepared.

Embodiment 3

[0048] The difference between Example 3 and Example 1 is that in Example 3, silver nitrate (AgNO 3 ) replace the zinc chloride (ZnCl 2 ), and other preparation processes were the same as in Example 1. The finished product 3 of the multifunctional fiber dressing was prepared.

Abstract

The invention belongs to the technical field of medical materials, and discloses a coordination compound as well as a preparation method and application thereof. The coordination compound is prepared from anthocyanin and metal ions; the anthocyanin has very high oxidation resistance and good antibacterial performance, and phenolic hydroxyl groups in the anthocyanin structure can be chelated with the metal ions, and can also chemically react with amino, sulfydryl, hydroxyl or carboxyl and the like on the surface of biological tissue under a mild condition to generate covalent bonds; and wound skin tissue is chemically anchored, and strong adhesive force is provided by forming the covalent bonds, so that wound adhesion and tissue repair in a wet state are realized, namely, a metal-polyphenol coordination polymerization principle is adopted for preparing the anthocyanin-metal ion coordination compound. According to the invention, a stent material is prepared by using an electrostatic spinning technology, a multifunctional electrospun fiber dressing capable of realizing in-situ monitoring and treating of bacterial infection is prepared by loading the anthocyanin-metal ion coordination compound, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a coordination compound and its preparation method and application. Background technique [0002] The skin is the body's natural barrier, protecting the body's internal tissues and organs from the outside world, while sensing and regulating body temperature. When the skin is subjected to some inevitable physical, chemical and biological damages such as burns, surgical wounds, war wounds, bacterial infection and foot ulcers, etc., it will cause skin wounds, and once the skin wounds are formed, the human body loses the first natural protection The barrier, bacteria and other pathogenic microorganisms will colonize, multiply and infiltrate the wound surface, often causing wound infection. Wound infection often leads to delayed wound healing. Severe wound infection may cause immune dysfunction, systemic infection, sepsis, septicemia, or cause chronic inflammati...
