Abstract

The invention relates to a cereals alcohol-soluble protein conduit and a preparation method thereof in the field of biomedical technology; the method comprises the following steps: cereals alcohol-soluble protein and organic solvents are mixed to obtain protein solution; after the protein solution is extracted by a mold, drying treatment is carried out and the protein pipe is demoulded from the mold; secondary extraction is carried out to the protein pipe, so as to form a nanoscale spherical structure surface outside, and then form fixation is carried out; finally, conducting polymer is deposited on the protein conduit surface, so as to prepare the conductive cereals alcohol-soluble protein conduit. In the invention, the cereals alcohol-soluble protein is used as raw materials, and the protein conduit has good biocompatibility and degradation, is suitable for preparing tissue engineering conduits and is helpful for regeneration and functional rehabilitation of damaged tubular shaped soft tissues.

Description

technical field

[0001] The invention relates to a material in the technical field of biomedicine and a preparation method thereof, in particular to a cereal prolamin tube with an inner diameter of 0.2-12 mm and a tube length of ≤ 5 cm and a preparation method thereof. Background technique

[0002] The emergence of the concept of tissue engineering and its development in the past two decades have given us the hope to completely treat the damage and dysfunction of human tissues and organs. This is a new technology to directly obtain new tissues and new organs through cell culture. The most promising therapeutic method of the century [Liu Q, Tissue Engineering (tissue engineering), In: Biomaterials and Tissue Engineering, Shi DL ed, Beijing, Tsinghua University Publishing Press, 2004, p.195.]. In the field of tissue engineering research, biocompatible and degradable materials are usually used to induce regeneration of surrounding tissues or become temporary scaffolds for implan...
