Description
Technical field
The invention belongs to technical field of biological material, and in particular to a kind of fibroin hyaluronic acid mandruka and preparation method thereof and
Using fibroin hyaluronic acid mandruka produced by the present invention can be used for Wound dressing.
Background technique
Covering of the medical dressing as wound can substitute impaired skin and play temporarily in wound healing process
The barrier action of when property avoids or controls wound infection, provides suitable microenvironment for wound healing.In recent years, fibroin albumen, thoroughly
The natural high polymers materials such as bright matter acid are received significant attention as the application of functional dressing.Silk fibroin has excellent
Biocompatibility, mechanical performance and degradability, have a extensive future as bio-medical material.The moisturizing however, fibroin albumen absorbs water
Performance is insufficient, it is difficult to the microenvironment soaked for a long time is provided for the surface of a wound.Hyaluronic acid is a kind of natural mucopolysaccharide, in human skin
In be widely present, have excellent moisture-keeping function, be ideal natural moisturizing factor.Therefore, in conjunction with two kinds of natural high polymers
Feature can prepare the mandruka material with good structural stability and performance of keeping humidity, be used for Wound dressing.But
Since fibroin and hyaluronic acid belong to water soluble polymer, need when preparing intermingling material using chemical cross-linking agent.If
Can find it is a kind of mandruka material not soluble in water is prepared without using chemical cross-linking agent, for fibroin hyaluronic acid in life
Application and industrialization in object medical dressing will have great importance.
The fibroin albumen of freezing saves 2 by the patent report of Publication No. CN101502669B at -5~-25 DEG C~
60d obtains silk fibroin porous material not soluble in water.The patent report of Publication No. CN105749343A is by the silk of freezing
Fibroin saves 2~168h at 0~-7 DEG C and porous material insoluble under the acquisition hygrometric state that thaws at 37 DEG C.The preparation of these methods
Fibroin porous material is not needed using chemical cross-linking agent and denaturant, but single fibroin material water suction and moisture retention is poor.
Patent publication No. is a kind of fibroin albumen hyaluronic acid prepared by chemical cross-linking agent of the patent report of CN102836465A
Gel rubber material, by being crosslinked, hyaluronic acid significantly improves the water absorbing properties of fibroin material, but this method needs chemistry
The use of crosslinking agent.A kind of patent report of the Publication No. CN104497327A fibroin hyaluronic acid composite membrane of cross-linking agent-free
Preparation method, the blend film of water is insoluble in using drying and forming-film slow at 37 DEG C preparation, but film is as Wound dressing application
It is limited.There is research also to prepare fibroin albumen hyaluronic acid plural gel, but gel mechanical property using the method for ultrasonic wave induction
Difference is not able to satisfy the application of dressing, and ultrasonic wave acts on can degrade fibroin albumen and hyaluronic acid macromolecular weight.
