Cornea repairing material with matrix repairing capability and preparation method thereof

The invention discloses a cornea repairing material with matrix repairing capability and a preparation method thereof. The method comprises the following steps: (1) preparing a microRNA solution; (2) preparing a collagen solution; (3) preparing a collagen membrane; (4) preparing a gold nano-particle solution; (5) preparing a microRNA and gold nano-particle mixed solution; and (6) dropwise adding the mixed solution onto the collagen membrane to obtain the cornea repairing material with matrix repairing capability. The cornea repairing material has a laminar structure, has the advantages of good transparency, high moisture content and excellent ion permeation performance, and can be used for effectively reducing and retarding occurrence of cicatrix repairing. The cornea repairing material with matrix repairing capability can be used for repairing a damaged cornea matrix in the medical field, is prepared from low-price and easily available raw materials, is simple in preparation process and simple in equipment, and has excellent application prospects and scientific values.
