Claim 0:
1. A method of preparing a hydrogel for a treatment of a bacterial infection, wherein the bacterial infection is an ocular infection or an epidermal infection caused by methicillin-resistant Staphylococcus aureus;
the hydrogel is prepared from ferrous sulfate, ascorbic acid, and hyaluronic acid;
the method of preparing the hydrogel comprises steps of:
S1, dissolving the ferrous sulfate and the ascorbic acid in water to make a mixed solution and heating the mixed solution to 45-55° C., wherein a concentration ratio of the ascorbic acid to the ferrous sulfate is 1:1;
S2, adding the hyaluronic acid during a heating process and stirring until a stable colloid is formed to obtain the hydrogel, wherein an amount of the hyaluronic acid added is 2% of a mass of the mixed solution,
wherein the mixed solution in S1 includes 1 mM ferrous sulfate.
