Problems solved by technology

[0003] Liposome has developed rapidly as a new type of drug carrier in the field of medicine. Liposome is a bimolecular vesicle composed of phospholipid molecules. As a drug carrier, liposome has many advantages: It can encapsulate fat-soluble drugs and water-soluble drugs. It can effectively protect the encapsulated drugs, improve bioavailability, make the drugs have eight functions, and reduce the toxic and side effects of drugs. Liposomes have the function of slow and controlled release. , suitable for multi-way drug delivery, etc. Due to its unique structural characteristics, liposomes, as a new type of drug carrier, have brought pharmaceutical preparations into the new world of targeted drug delivery, and have received increasingly widespread attention in the medical field. Liposomes are mainly It is a bilaye

Abstract

The invention belongs to the technical field of medical health and biomedical materials, and particularly relates to a polyphenol modified lipidosome nano system. The polyphenol modified lipidosome nano system comprises lipidosome, polyphenol, an oxidizing agent, a buffer solution serving as a reaction solvent and a hydrothermal reaction kettle with a polytetrafluoroethylene lining. The preparation method comprises the following steps of preparing lipidosome by adopting a film drying method, and preparing the polyphenol modified lipidosome nano system by adopting a one-pot hydrothermal method; and the lipidosome is more easily permeated into the cuticle of the skin and can be well distributed, degradation and deterioration of many active substances can be prevented due to the wrapping effect of lipidosome, and polyphenol has rich and complex physical and chemical properties and has wide chemical purposes including ultraviolet absorption, free radical removal and metal ion complexation. The system is also commonly used for promoting delivery of protein, nucleic acid and conventional drug molecules, so that the system can be used as a universal platform for delivering protein, nucleic acid, conventional drug molecules and the like; and the preparation method is simple and convenient, short in reaction time, low in cost, environment-friendly and safe.
