Description
Technical field
The invention belongs to the preparation field of silk fibroin nano-fiber, particularly relate to a kind of preparation method with silk fibroin nano-fiber of skin-care effect.
Background technology
Fibroin albumen is to be come unstuck by silkworm, is a kind of natural protein, has excellent performance such as excellent biological compatibility, biodegradability, high ventilation, poisture-penetrability, non-immunogenicity
[1,2]Be widely used in the reparation and the regeneration of tissues such as skin, bone, cartilage, tendon, nerve trachea, blood vessel.Park etc.
[3]The silk fibroin nano-fiber film that is equipped with for the solvent electro-spinning with formic acid can promote mouse preosteoblast (MC3T3-E1) to adhere to, breed, break up, and can induce the generation of BGP, promotes bone tissue restoration and regeneration.
Fibroin albumen has outstanding skin-protection and health-care effect.Fibroin albumen contains 18 seed amino acids and polypeptide composition, and wherein glycine, the third atmosphere acid and 3 kinds of simple amino acid of serine occupy 85% of Tot Prot, and are very approaching with the skin and the hair of human body, thereby becomes the popular research material of artificial skin
[4]Fibroin albumen also has good moisture preserving property and heat insulating ability, can help skin to regulate moisture, and its mechanism is identical with the interior natural moisturizing factor of human body
[5]Research confirms that fibroin albumen also has the effect that solar radiation is resisted in the absorption ultraviolet ray, and the melanin that can effectively suppress in the skin generates
[6-8]Therefore, fibroin albumen is good skin care products base material.
Vitamin is the general name of the indispensable small molecule active material of human body, and it can not synthesize in human body, perhaps can not capacity synthesize, and must absorb from the external world.Vitamin is participated in biochemical reaction widely in vivo as the auxiliary element of some important enzymes, has determined some crucial metabolic process.Many vitamins come to light and skin health has substantial connection, thereby usually appear in some skin-protection products as additive
[9]Vitamin C has many maintenance functions to skin; Being described as " beauty treatment vitamin ", is remarkable anti-oxidant, can help to reduce the infringement of radical pair skin; Help to reduce wrinkle and improve skin texture, and the generation that suppresses dermal melanin, the melanic effect that desalination has generated are arranged
