Abstract
The invention provides a composite nanofiber membrane dressing with high oxidation resistance and antibacterial property, which is characterized in that phillyrin is added into a sodium alginate solution, and then a nanofiber membrane is obtained through electrostatic spinning; and then, crosslinking by adopting 2 wt% of calcium chloride solution to obtain the composite nanofiber membrane dressing. According to the invention, the carbon dots are utilized to improve the sodium alginate nanofiber membrane, so that the high-concentration sodium alginate electrostatic spinning membrane can be prepared, has high hygroscopicity, and also has high biocompatibility, and then the fructus forsythiae is loaded on the nanofiber membrane, so that the nanofiber membrane is endowed with high oxidation resistance and high hygroscopicity, the excessive active oxygen of a wound is reduced, and the excessive wound exudate is absorbed. Meanwhile, the nanofiber membrane has better antibacterial performance. Can greatly accelerate the healing speed of the wound.
Description
Technical Field
The invention belongs to the technical field of biomedical articles, and particularly relates to a composite nanofiber membrane dressing with high oxidation resistance and antibacterial property.
Background
Wounds are one of the common ailments in daily life, and the adhesion of wound exudates and common dressings can delay the healing of wounds and cause secondary injury. Many of the existing biological dressings use nano silver ions as an antimicrobial agent, which may cause some body discomfort. Currently, the use of biological dressings with natural antimicrobial agents to promote wound healing has become a major trend.
The nanofiber membrane dressing studied in the past has single performance and cannot adapt to complex wound conditions. Therefore, it is of great significance to develop a multifunctional nanofiber membrane as a dressing.
Disclosure of Invention
The invention aims to provide a composite nanofiber membrane dressing with high oxidation resistance and antibacterial property, thereby making up the defects of the prior art.
The invention firstly provides a composite nanofiber membrane dressing, which is characterized in that phillyrin is added into a sodium alginate solution, and then a nanofiber membrane is obtained through electrostatic spinning; and then, crosslinking by adopting 2 wt% of calcium chloride solution to obtain the composite nanofiber membrane dressing.
Furthermore, carbon dots are also added into the sodium alginate solution;
preferably, the concentration of the sodium alginate solution is 92%.
The composite nanofiber membrane dressing has a specific preparation method as follows:
1) mixing a sodium alginate aqueous solution and a polyethylene oxide aqueous solution, adding a surfactant, dimethyl sulfoxide, 0.5 wt% of phillyrin and 0.2 wt% of carbon dots, and stirring at normal temperature to obtain a spinning solution;
2) preparing the spinning solution into a nano cellulose membrane by an electrostatic spinning method;
