[0035] Example 1, preparation of polypeptide growth factor modified hair-based material
[0036] 1. Preparation method
[0037] Prepare the polypeptide growth factor modified hair-based material according to the following steps:
[0038] (1) Preparation of hair-based material treated with hydrochloric acid
[0039] Take hair with a length of 1cm (scanning electron microscope photo as figure 1 As shown in A), several roots were soaked in an aqueous solution of 75wt% alcohol for 60 minutes at a temperature of 37°C, washed with distilled water and dried at a temperature of 37°C for 15 minutes. Then 8 mg of hair is placed in 10 mL of hydrochloric acid aqueous solution with a mass concentration of 10%, and soaked for 10 min at 37° C.; after the reaction is completed, it is rinsed with distilled water and freeze-dried for 36 h to obtain the hair-based material (scanning electron microscope photo as shown in figure 1 shown in B).
