The invention discloses a half-path charge complementary type chiral self-assembled short-peptide nanometer biomedical material and application. The general formula of the amino acid sequence of a chiral self-assembled short peptide provided in the invention is shown as follows: Ac-Pro-X-Phe-Y-Phe-Asn-Phe-Gln-Pro-NH2, wherein X and Y are polar charged amino acids, X is an negatively charged amino acid and Y is an positively charged amino acid, the amino acids of the whole peptide chain are all D-amino acid, and the number of amino acid residues is set as 9. The half-path charge complementary type chiral self-assembled short peptide has a secondary structure with relatively strong stability and is hardly influenced by external environmental factors, the self-assembly morphology of the chiral short peptide can be regulated by adding NaCl or changing the content of NaCl, and nanometer fiber hydrogel, which has rapid bleeding-stopping effect on bleeding wound, can be formed through self assembly. The material is simple and practicable in preparation technology and relatively low in cost, and the application of the material helps to enrich the kinds of nanometer biomedical materials.
